Heavy metal ion contamination in industrial wastewater is a major source of concern. Among the numerous approaches, biosorption has attracted the greatest attention in the removal of heavy metal ions from water. In particular, cadmium is bio-accumulative that poses a threat to our health when it exists in excess in our bloodstream. Here, the elimination of Cd (II) ions from wastewater using adsorbent derived from rubber seed shell (RSS). Further, thermogravimetric analysis was performed to determine the stability of materials. According to the hard and soft acids and bases (HSAB) principle, the rubber seed shell as novel bioadsorbent creates hard surface sites for cadmium ion adsorption. Batch experiments were carried out to determine the effects of pH, contact time, initial metal ions concentration, and biosorbent dosage on the removal efficiencies of Cd2+ ion using rubber seed shell. Adsorption isotherms and kinetics models were also performed for the elimination of Cd2+ ion. The optimum conditions was conducted and achieved 96% removal efficiencies of Cd2+ ion from water (pH 5.6, temperature 60°C, and initial metal concentration of 150 mg/L, the adsorption dosage 180 mg/g). The outcome of the present investigations indicated that the increasing use of bioadsorbent materials due to their low cost, regeneration ability, high adsorption efficiency, and higher removal percentage of metal ions from water sources.
A series of metal complexes containing a 1,10-phenanthroline scaffold, [ML] (L-1,10-Phenanthroline derivative comprises conjugated aromatic core); M=Cu(II), Zn(II), Co(II), & Zn(II) ions were designed and synthesized. The structural features of ligand and its metal complexes were elucidated using analytical and spectroscopic techniques. Based on the analytical and spectroscopic data suggested that a square planer structure with moderate distortion was attributed to the above metal chelates. The distorted square planar geometry of the copper(II) complex bound with DNA (Kb = 4.02´ 105 M-1) is stronger than that of ethidium bromide (EB) (Kb = 3.3´ 105 M-1) and other metal complexes, respectively. The synthesized 1,10-phenanthroline derivative had the best inhibitory effects against acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE), with IC50 values of 0.48 and 3.4 µM, respectively, which were lower than the standard. The experimental observations may contribute to the development of new drug molecules particularly in the treatment of neurological disorders including glaucoma, Alzheimer’s disease and diabetes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
