Abstract

Abstract:

With K-feldspar as raw material,MnO₂ was loaded on the surface of K-feldspar to prepare the composite adsorption material of MnO₂/Kfs.The influence of different factors on the adsorption performance of this composite material was studied by static adsorption test,and the adsorption isotherm properties,adsorption kinetics,and adsorption thermodynamic were also researched.Results showed that the increase of initial pH,MnO₂/Kfs dosage,adsorption time and temperature were all benefit for the adsorption of MnO₂/Kfs on Ni ²⁺.With the MnO₂/Kfs dosage of 0.20 g,initial pH of 6,temperature of 298 K and adsorption time of 10 h,the adsorption rate of MnO₂/Kfs on Ni ²⁺ reached 90.68% in 20 mL Ni ²⁺ solution with the initial mass concentration of 100 mg/L.The adsorption process fitted with the pseudo-second-order kinetics model and Langmuir adsorption isotherm model respectively.Above results indicated that the adsorption of MnO₂/Kfs on Ni ²⁺ belongs to monolayer chemisorptions.The theoretical maximum adsorption capacities of the MnO₂/Kfs are 14.217,22.114,27.218 mg/g when the temperature are 298,308,318 K respectively.The adsorption thermodynamic results indicated that this adsorption process is a spontaneous,endothermic and entropy increasing process.After reused for 4 times,MnO₂/Kfs still had high adsorption rate for Ni ²⁺ and good regeneration performance.

Key words: K-feldspar, loading, Ni ²⁺, adsorption kinetics, adsorption thermodynamic
