(3) Adsorption at adsorption equilibrium was achieved after 3h, the adsorption capacityremained at 300 mg/kg above, grapefruit peel activated carbon adsorption of phosphate follows thequasi-second order kinetic model; Freundlich R'correlation coefficients were significant, therefore,grapefruit peel activated carbon adsorption of phosphorus found Freundlich isotherm model;initialconcentration, dosage, pH and adsorption temperature on adsorption of phosphorus are affected, pH onthe adsorption of non- large.gold adsorption on activated carbon
(4) Adsorption at adsorption equilibrium was achieved after 14h, the adsorption capacityremained at 21.5 mg / g above. Grapefruit peei activated carbon Cr () in the adsorption processfollowed pseudo second order kinetic model; by the Langmuir equation and Freundlich equation of thecorrelation coefficient R' known,consistent with Langmuir isotherm model and the Freundlichisotherm model.Using Langmuir isotherm model to analyze the experimental data obtained in thesolution pH 4, the maximum adsorption capacity was 26.25mg / g;Freundlich isotherm model using>www.chinactivecarbon.com
