Removal of Lead Ion in Waste Water by Coprecipitation and Flotation Methods

Methods of Nickel Removal from Valerian Irrigating Waste Water

Industrial development and extensive use of heavy metals have led to the problem of environmental pollution. Nickel compounds are toxic to plants and have detrimental effects on their growth. Valerian is a plant used in herbal medicine. Considering the hazards of nickel, various methods have been developed to remove this contaminant from herbs irrigation wastewater, including the common chemica...

Removal of Lead Ions from Aqueous Solution by Sorptive-Flotation Using Limestone and Oleic Acid

A simple, rapid and economic procedure was presented to remove lead(II) from aqueous solution under the optimized conditions. It is based on the sorption of Pb2+ ions from aqueous solutions onto limestone fines (LS), which is an inexpensive and widespread over the globe, followed by flotation with oleic acid (HOL) surfactant. The different parameters (namely: solution pH, sorbent...

Lead Removal by Waste Organic Plant Source Materials Review

Many works have been made by research scholars to remove lead from wastewaters using different sources of organic materials derived from plant origin. In this paper an attempt has been made to review different sources of waste organic materials and the respective carbon materials which have been used for the removal of lead(II) from water and wastewater based on recent literature review.

Thermodynamic 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...
