Adsorption study of Zinc ion onto halloysite nanotubes using taguchi’s design of experimental methodology

Design of Dye Adsorption by Amine Terminated Dendritic Functionalized Halloysite Nanotubes Using Response Surface Methodology (RSM)

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...

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...

Thermodynamic Study of Hg(II) Ion Adsorption onto Nano Hydroxyapatite from Aqueous Solution

Hydroxyapatite nanocrystals were synthesized by sol-gel combustion method for the sorption ofHg(II) ions from aqueous solutions. The effects of varying parameters such as pH, temperature, initialmetal concentration, and contact time on the adsorption process were examined. Adsorptionequilibrium was established in 360 minutes and the maximum adsorption of Hg(II) on thehydroxyapatite was observed...

Study Kinetic and Isotherm adsorption of Reactive Blue 39 onto nano Zinc hydroxide chloride

Zinc hydroxide chloride nanostructure was successfully synthesized through a simple method at low temperature by sonochemical process. The morphology and crystalline of the products were analyzed by XRD, FESEM and TEM. The effect of independent variables including contact time, solution pH, adsorbent dosage and the concentration of dyes on response performance with response to surface methodolo...
