离子交换树脂为一门比较年青的应用科学,由于它在工业上、医药上、农业上和原素分离上特别由于在原子能利用方面,有很重要的价值,所以近十年来发展得很快。最初应用在工业上的离子交换剂为一种天然无机硅化合物,俗名沸石,在我国抚顺藏量很丰富;后来又有合成沸石。可惜这种交换剂稍能溶解于水,且稳定性低,用作软化水时不能在 Ion exchange resin is a relatively young applied science. It has developed rapidly in recent ten years because of its important industrial, medical, agricultural and pro-elemental separations, especially for its use in atomic energy. Originally used in industrial ion exchangers for a natural inorganic silicon compounds, common name zeolite, Fushun in our country is very rich in reserves; later synthetic zeolite. Unfortunately, this exchange agent slightly soluble in water, and low stability, can not be used as a softened water
