| Abstract: | The adsorption and desorption properties of strong base anion exchange resin for picric acid were investigated,and the adsorption thermodynamics,kinetics and mechanism were also studied.The experimental results show that: The adsorption quantity of picric acid is increasing with the increase of adsorption temperature;When the solution pH is 2.7-12.0,the adsorption quantity is the maximum with above 120 mg/g;The adsorption isotherm of picric acid on resin accords with Freundlich model and the correlation coe... |
