Aspects of the Hydro-geochemistry of Groundwater in Agbor/Owa Communities of Delta State, Nigeria| Chapter 2 | Research Aspects in Chemical and Materials Sciences Vol. 4

 The essences of barium, calcium, sodium, sulphate, phosphate, and cyanide in groundwater in Boji-Boji (BB) area and suburbs of Ika land, Delta state, Nigeria, were examined. Without some form of treatment, groundwater is the basic source of water for the locals of these societies. The essence concerning this exercise is to study few facets of the hydro-geochemistry of groundwater in these communities to authorize its excellence for devouring and the sustainable welfare of the people. There are 55 borehole water sites spread across these five sample substitute-fields. Solar Unicam flame Atomic Absorption Spectrophotometer was used to analyse the metal ions. The colorimetric system was used to determine the sulphate, phosphate, and cyanide elements of larger object. The results show the ghost of sodium, calcium, sulphate, and phosphate. However, barium and cyanide were below the discovery limit. Second, the aquifer held a greater proportion of calcium and sulphate than sodium and phosphate.Third, a mean percentage value of 0,018 and 0.158 were noticed for Na+/Ca2+ and PO43-/SO42- individually. Fourth, sodium had a strong equating with all of the different limits. Finally, the concentrations of the studied limits are below the WHO's maximum contaminator levels, meaning that the water is free of analytes. However, the sodium concentrations in many sample fields continue to cause concern from a strength belief.

Sulphuric Acid Bake-Leach Process for the Treatment of Mixed Copper-Cobalt Oxide Ores: An Experimental Study | Chapter 2 | Research Aspects in Chemical and Materials Sciences Vol. 2

For the treatment of mixed copper-cobalt oxide minerals, a sulphuric acid bake-leach process was investigated as an alternative to reductive leaching. On the dissolution of copper and cobalt, the effects of acid dose, baking temperature, baking duration, and leaching time were examined. The combined copper-cobalt oxide ore was treated with sulphuric acid before being baked in a muffle furnace. The reacted samples were subjected to water leaching at room temperature to examine the leachability of copper and cobalt from the baked material.

Acid concentration affected the dissolution of copper and cobalt differently, with cobalt being more sensitive to acid concentration. Copper and cobalt were quickly removed from the baked material without the application of reducing agents. For copper-cobalt oxide ores, the sulfuric acid bake-leach process has been found to be a practical substitute for the reductive leaching approach.

Assessment and Analysis of Water Quality Parameters of Groundwater Near Ranebennur Industrial Area, Haveri District, Karnataka, India | Chapter 2 | Challenging Issues on Environment and Earth Science Vol. 1

This paper presents an evaluation of the groundwater quality of industrialised villages in Ranebennurtaluk, Haveri district, Karnataka, India. In order to measure the quality of groundwater for evaluating its fitness for domestic us e, five villages affected by industrialization were chosen for the present analysis. Groundwater is an important source of water for the survival of human life and the protection of the environment. For drinking, irrigation and industrial uses, groundwater is the most vital source of water. Bore well samples were tested for physico - chemical variations and groundwater quality from each village. Comparison of Physico - findings of chemical analysis with Indian Standard drinking water limits shows that all but a few groundwater samples are fit for drinking and irrigation purposes. For five villages, the average pH value is 7.5-8.0, which is within the desired range. The pH value is growing, however, so it may not be ideal for future use. More than 1000 is around 75% of the EC and TDS values, but it is acceptable. Around 50% of chloride-containing water samples greater than 250 mg/l are considered undesirable for drinking purposes, which can lead to cardiovascular diseases. For each sample of villages, the sulphate concentration is within the desirable limit. It is also found that 25 percent of samples containing more than 300 mg/l of total hardness are undesirable. There could be a chance of deteriorating groundwater quality in the future. The quality of groundwater can be enhanced by the adoption of waste water treatment plants in industries that cause these aquifers to be contaminated.
