Preparation of a Novel Cation Exchange Resin PSSS-g-CD301 and its Adsorption Properties towards Metal Ion

Abstract:

Resin D301 was surface-carbonized to obtain the surface charring materials (CD301). Using redox initiating system constituted by the amino groups of CD301 particles and persulfate in the solution, the poly (sodium styrene sulfonate) (PSSS) was grafted onto the surface of CD301, obtaining the grafted material PSSS-g-CD301, and the degree of grafting can reach 17.7% under suitable conditions. PSSS-g-CD301 was characterized by infrared spectrum (FTIR), and the degree of grafting was measured by gravimetric method. The adsorption character of PSSS-g-CD301 towards Al³⁺, Fe³⁺ and Cu²⁺ were mainly examined and investigated. PSSS-g-CD301 possesses strong adsorption ability towards Al³⁺, Fe³⁺and Cu²⁺. The adsorption capacity can get up to 13.285mg·g^-1, 14.864mg·g^-1, and 15.10mg·g^-1, respectively. The data of isothermal adsorption matched well with Langmuir equation. The adsorption capacity increased with the increase of temperature and the value of pH. The adsorption capacity of PSSS-g-CD301 towards Fe³⁺ changed little after use them six times.
