Objective:To introduce a new rapid detennination method of cations and anions in dialysis solution for artificial kidney.Method.The single column cationioc coromatography and the double columns anionic chronatograny were used to determine cations(Na+,K+,Ca2+,Mg2+)and anions (Ac and CI)respectively,Results Linear responses have been obtained in the following ranges for Na+,K+,Ca2+,Mg2,Ac and CI,respectively:0.01-10(t=0.9996),0.05-10(r=0.9978).0.05-10(r=0.9964).0.09-20(r=0.9995),0.03-10μg·mL-1(r=0.9996).The reprodueibility was also good(RSD4%.n=5).Conclusion.The results showed that it is a quicl and simple method with convenience,accuracy and sensitivity,Therefore,it can be applied in rapid qualitative and quantitative determination of cations and anions in dialysis solution for artilicial kidney.
