Adsorption Equilibrium and Kinetics of Lead Ion onto Synthetic Ferrihydrites
Batch experiments were conducted to study the adsorption behaviors of lead ion (Pb2+) onto ferrihydrites prepared using three different procedures which were characterized by textural analysis (BET). The adsorption removal of Pb2+ by the three ferrihydrites (called FH-1, FH-2 and FH-3, respectively) were compared, and FH-3 shows fast adsorption kinetics as well as hig...
متن کاملPreconcentration of Trace Vanadium with the Ion Pair of 2-Nitroso-1-Naphthol-4-Sulfonic Acid and Tetradecyldimethylbenzylammonium Chloride Onto Microcrystaline Naphthalene and Determination by Derivative Spectrophotometry
Vanadium is quantitatively retained on 2-nitroso-1-naphhthol-4-sulfonic acid tetradecyldimethlbenzyammonium chloride onto microcrystalline naphthalene in the pH range of 3.0-4.0 from a large volume of aqueous solutions of various alloys and synthetic samples. After filtration, the solid mass consisting of the vanadium complex and naphthalene was dissolved with 5.0 mL of dimethylformamide an...

متن کاملThermodynamic study of lead ion removal by adsorption onto nanographene sheets
A batch adsorption study was applied to investigate the adsorption of Pb2+ ions from aqueous solutionby nanographene (nG).The adsorption percentage of Pb2+ions onto nG samples at different initial pH,contact time (tc), adsorbent dosage (mnG) and temperature (T) were investigated. The results showedthat nG is an excellent adsorbent for Pb2+ions removal from aqueous solutions with an adsorptionpe...
متن کاملReview of preconcentration and solid phase extraction for the determination of trace Lead
Spectrometric techniques for the analysis of trace lead have developed rapidly due to the increasing need for accurate measurements at extremely low levels of this element in diverse matrices. This review covers separation and preconcentration procedures, and considers the features of the application with several spectrometric techniques. The use of an appropriate sample handling technique is a...
