Abstract: The properties,optimal conditions and influencing factors for polyamide resin to adsorb 2,4-binitro-phenol from aqueous solutions have been investigated.The results show that polyamide has a better adsorption capability,and that the pH value is the main factor affecting adsorption;the initial rate of 2,4-binitro-phenol adsorption on polyamide is faster,and the middle rate is second-order with respect to its concentration.The adsorption process in solution exhibits Freundlich behavior and is mainly physical adsorption.The 2,4-binitro-phenol adsorbed on the resin can be eluted by 1% ammoniac solution quickly.
