改性木质素磺酸钠对铅离子的吸附行为研究
Adsorption Behavior of Lead Ion on Modified Sodium Lignosulfonate
摘要
Abstract
Lignosulfonate modified by hydrogen peroxide and sodium sulfite on adsorption of lead ion in aqueous solution was studied. Effects of initial metal ion concentration,pH values,adsorption temperature and time on adsorption behaviors were explored. The results show that the equilibrium adsorption capacity of lead ion increases with the pH values rising from 1.5 to 5;while the effect of adsorption temperature is not obvious on the equilibrium adsorption capacity. Under the optimal adsorption condition,the adsorption of lead ion gets adsorption equilibrium at 120 min,and the saturated adsorption amount of lead ion is up to 55.22 mg/g. The results of thermodynamics study demonstrate that the adsorption of lead conforms to Langmuir adsorption isotherm and the pseudo-first-order kinetics equation.关键词
