Adsorption of Phosphorus and Its Fertilization and Porous Sorbent Using Calcium and Dissolving Magnesium | Chapter 8 | Chemical and Materials Sciences: Developments and Innovations Vol. 7

Aims: The aim of this research was to investigate Magnesium hydroxide [Mg(OH)₂] and nano calcium treatments for the utilization of spent coffee grounds (SCG) and formed waste glass. Adsorption of phosphate, potassium, and phosphate on the surface of the magnesium-modified SCG or formed waste glass was measured. The effect of the potassium magnesium phosphate formed on the SCG and nano calcium phosphate on plant growth was evaluated.

Methods: The adsorption characteristics for phosphorus and potassium were studied using a batch method to determine the effect of the magnesium concentration on the modified SCG and the side effects of nano calcium.

After adsorption, the modified SCG product and nano calcium phosphate were applied to the soil, and plant growth tests were carried out in pots.

Results: The maximum phosphate adsorption (65.89% at a phosphate concentration of 45.98 mg/g) was obtained with 2.5 M Mg(OH)₂. When the post-equilibrium pH was close to 9, the ratio of the changes in the concentrations of potassium to phosphate was 1:1, and potassium magnesium phosphate formed on the surface of the modified SCG. The use of nano calcium resulted in a high adsorption capacity of 62 mg/g phosphorus. By considering separation and supporting it on foam glass, a removal rate of more than 90% was achieved for a phosphoric acid solution with an initial concentration of 100 mg/l.

Conclusion: Calcium hydroxide and nano-sized calcium with low solubility could also be supported on inexpensive porous materials to show the ability to recover phosphorus and potassium, or higher adsorption capacities. The potassium magnesium phosphate and calcium phosphate, produced per carrier, were mixed with soil and used in planting experiments, which demonstrated a discernible impact on growth. The application of a fertilizer prepared from EMSCG was observed to have a beneficial effect on the growth of R. sativus, resulting in an increase in both plant height and leaf width in comparison to the control (no treatment).

Phenoplastic Potentials of Cocoyam Species Exposed to Selected Environmental Stressors | Chapter 8 | Progress in Chemical Science Research Vol. 8

 Investigation of the belongings of two oilfield chemical compound on the morphology of few cocoyam accessions was carried out. Accessions of Colocasia esculenta and Xanthosoma maffafa were unprotected to graded concentrations of sodium thiosulphate and element powder. The following concentrations (5, 10, 20 and 400 mg/kg) of sodium thiosuphate and graphite powder individually were used to the accessions while unpolluted soil dressed as the control experiment. Observations revealed that the poisoned accessions had increased plant climax and better yields than the control. Some X. maffafa accessions polluted accompanying sodium thiosulphate produced distorted leaves. Cocoyam accessions generally displayed poor material bioindicator potentials hence, soil estimates and further studies on lands that would be secondhand for cocoyam help were advocated.

Natural Medicinal Flora of Three Gorges of Yangtze River (Part of Rare and Endangered Medicinal Plants) | Book Publisher International

 The natural medicinal flora of the Yangtze River's three gorges was the subject of this book. This book seeks to give academics and practitioners of traditional Chinese medicine with information on natural medicinal plants found in China's Three Gorges region. This book examines the natural environment, vegetation composition, distribution law, and floristic composition of natural medicines in depth, based on a systematic field examination of natural medicinal plants in China's Three Gorges region. The book serves as a useful guide for experts and may also be utilised as a reference book.

Recent Comparative Analysis of the Phytochemicals, Proximate and Mineral Compositions of Scent Leaf (Ocimum gratissimum) and Bitter Leaf (Vernonia amygdalina) Leaves | Chapter 9 | Current Advances in Chemistry and Biochemistry Vol. 4

 Plant-based medicines have the advantages of being convenient, safe, and having a wide spectrum of action. An ethnobotanical and ubiquitous plant provides abundant natural drug tools for research and development. In Southern Nigeria, the vegetables Ocimum gratissimum (fam. Lamiaceae) ‘Scent leaf' and Vernonia amygdalina (fam. Asteraceae) ‘Bitter leaf' are widely eaten. The ‘Igbos' of South East Nigeria use O. gratissimum to flavor soups and stews, while the ‘Yorubas' of South West Nigeria use it to treat stomach problems. V. amygdalina is a well-known West African vegetable that is used for both nutritional and medicinal purposes. The widespread consumption of these vegetables prompted the current research, which aimed to establish the food compositions, mineral constituents, and phytochemicals of the two vegetables. Saponins, terpenoids, tannins, flavonoids, hormones, alkaloids, phenolics, and anthraquinones were found in both vegetables after qualitative examination of the aqueous extracts. V. amygdalina had higher levels of secondary metabolites than O. gratissimum, with saponin being the highest at 5.710.12 mg/g and 3.520.01 mg/g, respectively. Terpenoids were next at 5.640.11 mg/g and 3.400.11 mg/g in V. amygdalina and O. gratissimum. The two vegetables do, however, contain a trace amount of anthraquinone. The macro elements and proximate analysis were calculated using various standard methods. In V. amygdalina and O. gratisimum, proximate analysis showed the presence of moisture (12.28 0.02 percent and 10.01 0.01 percent, respectively), protein (35.370.11 percent and 22.200.02 percent), and total ash (6.000.20 percent and 5.750.10 percent). Calcium, magnesium, potassium, sodium, iron, copper, and zinc were among the minerals found. The highest concentrations of zinc (46.80 0.03 mg/kg and 58.000.12 mg/kg) were found in V. amygdalina and O. gratissimum, respectively, followed by copper (9.450.11 mg/kg and 16.60 0.03 mg/kg). V. amygdalina has higher levels of phytochemicals and food components, while O. gratissimum has higher mineral content. These two vegetables are possible sources of complementary medicine components.

Thripidae (Thysanoptera) Species Collected from Common Plants and Crops in Peninsular Malaysia: New Perspectives | Chapter 12 | Current Research in Science and Technology Vol. 4

A list of 66 species of thrips recorded from crops or plants in Peninsular Malaysia is presented. Most of the specimens came from a substantial survey of cultivated plants and one-third were from the genus Thrips. The specimens were collected by beating vegetation (that is, either the flowers or leaves) over a plastic tray, subjected to a standard dehydration and clearing process before being slide mounted. Slide mounted specimens were then identified using taxonomic keys. This study also recorded another twenty-one species of thrips besides the two former species from Malaysia: Frankliniella schultzei, a polyphagous tospovirus vector and Stenchaetothrips biformis, the rice thrips. The study reveals 66 species recorded as associated with cultivated plants in Malaysia; of these, 43 were found on more than one species of plant.
