A pot incubation study was conducted to investigate the feasibility of using Daucus carota var. sativa (carrot) and Brassica juncea var. multiceps (potherb mustard) for phytoremediation of Cd-contaminated soils and evaluateing the effects of chelating agents (EDTA, EGTA, DTPA and citric acid) application on metal uptake by both plants. It was shown that, the content of water soluble and exchangeable...
The study evaluated the sorption of Cd(II) or Zn(II) ions from aqueous solution by a new biosorbent, rice bran. The rate and extent of accumulation were affected by chemical treatment of rice bran, pH, contact time and initial metal ions concentration. When each metal ions initial concentration was 100 mg/L, pH 6.0, contact time 30 min, NaCl 0.1 mol/L treated rice bran 1 g/L, the removal efficiency...
An anion exchange-sequential injection hydride generation atomic fluorescence spectrometric procedure was specifically developed for the determination of ultra-trace cadmium in pure copper forbidden by the Restriction of the use of hazardous substances in electrical and electronic equipment (RoHS). A 50 mg l −1 copper concentration was employed in the standard solutions to match the copper...
