Paper precipitation chromatography of mercury, copper, bismuth and cadmium with thioacetamide

Phytoextraction of cadmium, copper, zinc and mercury by selected plants

During the years 2006 and 2007 the phytoextraction ability of maize (Zea mays), willow-tree (Salix smithiana) and poplar (Populus nigra × P. maximowiczii) to accumulate cadmium, copper, mercury and zinc was investigated. Small scale field experiment was carried out on soil contaminated with chemicals from the waste incineration plant in Hradec Kralové (Czech republic). Screening of this allotme...

Capillary Gas Chromatographic Separation of Copper, Mercury, Lead and Cadmium as Complexes of Pyrrolidine Dithiocarbamate

Detection and separation of metals from fresh water and industrial effluents has become a pre-requisite for any nation in the world. In and around the city of Hyderabad (Sindh), Pakistan, the home as well as cottage industry which consumes chemicals containing the copper, mercury, cadmium and lead are freely dumped into local ravines and canals unchecked for many years. The process is polluting...

Cetylpyridinium Chloride Micelle-mediated Mutual Separation of Zinc, Cadmium, and Mercury Ions by Thin-layer Chromatography

Cationic surfactant-mediated systems containing different concentrations of cetylpyridinium chloride have been used as mobile phases in thin-layer chromatographic separation of metal cations on silica layers. The effect of surfactant concentrations below and above the critical micelle concentration (CMC) on the retention behaviour of metal ions was examined. The best TLC system for rapid mutual...

Effects of Glucose Concentrations on Cadmium, Copper, Mercury, and Zinc Toxicity to a Klebsiella sp.

The influence of glucose concentration on Cd, Cu, Hg, and Zn toxicity to a Klebsiella sp. was studied by following the degradation of C-labeled glucose at pH 6.0. Uptake of C into the cells was also determined. The carbon concentrations ranged from 0.01 to 40 mg liter, which are equivalent to soluble C concentrations in natural environments. The toxicity of Cu, Cd, and Zn to a Klebsiella sp. wa...
