Material and methods Preparation of heavy metal solutions The 100 ppm stock solutions of C d2+, Pb2+, Zn2+, Ni2+, Fe3+ and AsO43− ions were prepared by using CdCl2, Pb(NO3)2, Zn(CH3COO)2, Ni(NO3)2.6H2O, FeCl3·6H2O and Na2HAsO4...
Fig. 2 shows the concentration profiles of Zn(II) and Pb(II) with time in the batch cell having a configuration of Zn|NaCl (0.5 M)||PbNO3 (3.0 Â 10À4 M), NaCl (0.5 M) |RVC. For the process occurring in the cell, CP can be evaluated at a defined time from the ratio ...
Figure 2 The normal probability plot of the residuals for Pb2+removal byGelidium amansiibiomass determined by the first-order polynomial equation. Full size image The ANOVA of the Plackett-Burman design demonstrated that the model was highly significant as was evident from the Fisher’sF-test (39...
Dyes constitute an important group of organic contaminants and are recognized for its harmful effects on the aquatic environments and humans. Heavy metals are also the largest group of inorganic pollutants due to their accumulation in the environment, co
PbO nanoparticles were obtained by thermolysis of 1 at 180°C with oleic acid as a surfactant. The average diameter of the nanoparticles was estimated to be 33nm by the Scherrer equation. The morphology and size of the prepared PbO samples were further observed using SEM....
