The sorption behavious and mechanism of maoro-porous phorphoric acid resin for Cobalt(Ⅱ)ions were investigated. Macro-porous phcophonic acid resin has good adsorption ability for Cobalt(Ⅱ)in PH=3 HAC-NaAc. The Cobalt adsorbed on macro-porous phosphonic can be eluted by 2mol·l￣-1HCl quantitatively. The resin can be regenerated and reuscd without apparant decreasing ofsorption capacity.The saturated static adsorption capacity is 0.95 mmol Co(Ⅱ)/g· resin,The basic adsorption parameter and mechanism of macro-porous phosphonic acid resin for Cobalt(Ⅱ)werealso determined by chemical analysis and IR-spectrum.
