摘 要：正Introduction and Results Crown ethers,typically 18-crown-6 ether （18C6E）,have been used to improve the resolution of cations in ion chromatography [1-4]. For example,the addition of 18C6E in the eluent apparently increases the retention of potassium ion to improve the resolution. This is because the association constant of complexation between
