Data processing is an essential component of heavy-metal ion detection. Most the research now uses a conventional data-processing approach, which inefficient and time-consuming. The development efficient accurate automatic measurement method for ions has practical implications. This paper proposes CNN-based detection system, can automatically, accurately, efficiently detect type concentration i...

heavy metal pollution all around the world has become a major environmental concern and the bioremediation of polluted environments is an increasingly popular strategy due to both its efficiency and safety. in this study, a bacterial strain resistant to heavy metal was isolated from metal contaminated sites. strain mkh2 was removed pb (ii) with 95.06%. this isolate was also resistant to zinc, c...

the phenylthiourea-substituted triethoxysilane as a silane agent was synthesized and grafted on highly ordered nanoporous silica (lus-1) with a textured morphology and hexagonal array. this material (tu-lus-1) contained 0.8 mmol/g of soft base phenylthiourea group and surface area 760 m2g-1 and was able to adsorb 0.75 mmolhg/g of tu-lus-1 in endothermic reaction.

We have previously isolated a developmentally regulated novel gene, priA, from the basidiomycete Lentinus edodes. The deduced PRIA protein contains the two set of motifs similar to a 'zinc finger' typified by transcription factor TFIIIA and the motif of a 'zinc cluster' observed in metallothioneins. It also contains a hydrophobic N-terminal sequence. Here Escherichia coli cells producing PRIA w...

We developed a facile strategy for preparation of heteropoly metalate/graphene oxide nanocomposite as a new ion exchanger for cadmium ion removal from aqueous solution. The synthesized nanocomposite was characterized by X-ray powder diffraction (XRD), UV-Vis spectroscopy, FT-IR spectroscopy and Raman spectroscopy. Our findings indicated that the combination of heteropoly metalate nanoparticles ...

Understanding the speciation and binding of heavy metal ions in different environments is central to nuclear waste management processes. Due to the obvious safety and health hazard in experimental studies, theoretical calculations can be used as an alternative tool to study the chemistry of toxic heavy metal ions. Although several quantum chemical methods with variable accuracy are available, a...
