Eco-Friendly Adsorption of Methyl Red Using Biodegradable Sea Shells: An Isotherm Approach | Chapter 9 | Recent Developments in Chemistry and Biochemistry Research Vol. 9

Organic dyes have been identified as significant water contaminants. The use of low-cost, easily available, highly effective, and non-toxic adsorbents has been examined as an appropriate alternative to the available expensive techniques for removing dyes from effluent. This research aimed to investigate the utilization of Sea shells (SS) as an adsorbent material for removing Methyl Red (MR) dye from aqueous solutions. The influence of several factors: (contact time, pH, Temperature) on the adsorption ability of MR dye was evaluated. The results indicate that The optimum conditions were found: pH 3, 45 min contact time, and 300°C. Fourier Transform Infrared spectroscopy (FTIR) evaluates the chemistry of SS. The isotherm of Langmuir (R2 = 0.9531) was a better fit than the isotherm of Freundlich (R2 = 0.921) and Temkin isotherm (0.928) for data. The maximum monolayer adsorption efficiency was measured at 0.5 mg/g. The study found that SS is an excellent and inexpensive adsorbent for removing MR dye from solutions.

Aerobic Biodegradation of Malachite Green and Methyl Red by Klebsiella pneumonia KP 13 Isolated from Soil Contaminated with Laboratory Effluent | Chapter 1 | Research Advances in Microbiology and Biotechnology Vol. 5

 Synthetic dyes are established in the textile, bread, cosmetic, and paper publication industry. Due to their unruliness and persistence in the atmosphere they pose a threat to incidental health.The current study was completed activity to study decolorization of two such environmental contaminants, Methyl red,   an azo dye and Malachite green, a triphenylmethane dye by Klebsiella pneumonia KP 13 that was isolated from lab effluent adulterated soil of our college. Identification of the forceful isolate was attested by 16S r DNA method. Klebsiella pneumonia KP 13 was worthy utilizing Methyl coral and Malachite green as sole beginning of carbon in a medium holding 200 mgL-1 of di- ammonium hydrogen phosphate and 1000 mgL-1 yeast extract at best pH 7, temperature 37°C and under trembling conditions. Extent of decolorization of Malachite green and Methyl flaming was to in consideration of 85% and 93% respectively in 24 hours. Presence of nitrites in the decolorized samples of Methyl red rooted aerobic mode of biodegradation so ruling out composition of toxic scented amines.
