Nano-ZnO was employed for the adsorption of 4C2NP from aqueous solutions in batch equilibriumexperiments to investigate its adsorption properties. The quantity of 4C2NP adsorbed onto nano- ZnOsurface was measured by UV-Vis spectrophotometer. The effects of contact time, adsorbent dose, pH, andinitial concentration of 4C2NP were investigated. The adsorption found to be strongly influenced by all...

cationic copolymer gels of acrylamide and [(methacrylamido) propyl] trimethyl ammonium chloride (maptac) were synthesized by free radical aqueous solution polymerization. the taguchi method, a robust experimental design, was employed for the optimization of the synthesis based on the equilibrium swelling capacity of the hydrogels. based on taguchi method a standard l16 orthogonal array with fiv...

In this study adsorption of 1-chloro-4-nitrobenzene on single walled carbon nanotubes has been investigated.  The effect of contact time, pH, initial concentration of 1-chloro-4-nitrobenzene, adsorbent dosage and temperature on its adsorption has been carried out in order to find optimum adsorption conditions. Adsorption isotherms and related constants were also determined. Results showed that ...
