Chromium is a toxic heavy metal prevalent in higher levels in aqueous matrices owing to industrial applications. Whilst being a key player in industries, the environmental issues caused by Cr(VI) are highly deleterious. Adsorptive remediation is found to be an effective method adopted by researchers in the past decades for Cr(VI) removal from water...

Efficacy of Eucalyptus camaldulensis seeds in raw (ECS) and phosphoric acid activated form (PECS) in the remediation of Cr(VI) from simulated and electroplating waste has been checked in this study. Structural and physico-chemical characterization of the biosorbents have been elucidated using CHNS, Mercury intrusion porosimetry, FTIR and SEM-EDAX a...

Biosorption potential of Gliricidia sepium leaf powder (GSL) was investigated for elimination of hexavalent chromium (Cr(VI)) from synthetic waste-water. Behavioral effects on sorption of Cr(VI) over the biosorbent surface due to variation in pH, biosorbent-sorbate contact time, biosorbent dosage, initial chromium concentration, batch incubation te...

Hexavalent chromium contamination in water is an issue of huge concern due to its use at a high scale, toxicity and non-biodegradability. Biosorption is a cost effective and unconventional strategy for the elimination of Cr(VI). Here, a novel biosorbent Senna siamea seed pod biomass and its chemically activated form have been investigated for the e...

Cr(VI) removal was studied with Artocarpus heterophyllus peel as a biosorbent in batch and continuous mode. Parameters influencing the maximum removal efficiency like biosorbent dose, contact time, pH, temperature, agitation speed, initial chromium concentration have been optimized in batch studies. Cr(VI) removal was observed to be 99.92 percentag...

Hexavalent chromium pollution in water puts forward a huge threat to environment and human health. Conventional methods of heavy metal removal from water generate toxic by-products, which mandate the use of efficient and alternative biosorbent-based strategies. In this study, a novel biosorbent Pinus kesiya cone biomass has been investigated for th...

Fruit peel microparticles of Annona reticulata Linn were used as biosorbent for the sequestration of hexavalent chromium. Characterization of biosorbent was done using SEM-EDXS, FTIR, GCMS, CHNS, Mercury Intrusion Porosimetry and point of zero charge. Influential parameters were optimized using Response surface methodology with a total of 17 experi...

The present work utilized Ruellia patula Jacq leaves as biosorbent for hexavalent chromium removal. Sulphuric acid modification was done and checked for enhanced biosorption capacity. Electron microscopy-Energy dispersive x-ray spectroscopy, Fourier transform infrared spectrometry, elemental analysis were performed for characterization of biosorben...

In this study, batch removal of hexavalent chromium from aqueous solutions by powdered Colocasia esculenta leaves (CELP) was investigated. Batch experiments were conducted to study the effects of adsorption of Cr(VI) at different pH, initial concentration, agitation speed, temperature and contact time. The biosorbent was characterized by scanning e...

Lipases play a vital role in modern Biotechnology owing to their multifaceted properties. Their production and purification procedures need to be improved in order to enhance their stability and turn over. This work was done to study the effect of immobilization of whole cells of lactobacillus in the production of lipase in comparison with free cel...

This is most probably the first work in isolating genomic DNA from the dried tubers of Corallocarpus epigaeus (Ce), which is a medicinal plant, belongs to the family Cucurbitaceae using Cetyl Trimethyl Ammonium Bromide extraction method. Ultraviolet spectroscopy is done for the quantitative determination of DNA isolated. Antimicrobial activity of C...

RuelliapatulaJacq (syn: Dipteracanthus patulus) belongs to the family Acanthaceae, has numerous medicinal properties but is not exploited much in modern medicine. Invitro antimicrobial activity of the Ruelliapatulajacq leaves extracted with Ethanol, Methanol and Acetone was checked for Bacillus subtilis, Escherichia coli and Aspergillus niger by di...

Bartter's syndrome is a rare autosomal recessive disorder due to the mutation of the sodium potassium chloride cotransporter 2 gene (NKCC2) in the 15th chromosomes of Homo sapiens (15q15-15q21.1). This syndrome results in potassium wasting due to defect in reabsorption mechanism in thick ascending limb of loop of Henle (TALH), which leads to ionic...
