前言天然沸石用于海水提钾,沿海许多省市都在搞,我所学习了天津制盐研究所和中国科学院地质研究所的先进经验,于1976年初开始此项试验。海水提钾食盐水淋洗法,在这方面,我们做了一些补充试验,例如沸石变型的交换容量试验等。由于我省盐田卤水大部份未提取氯化钾,因此我们做了沸石用于卤水提钾的试验。为了节省用煤,我们采用氯化铵做淋洗液 Preface Natural zeolite used to seawater potassium, coastal provinces and cities are engaged in many, I learned from Tianjin Institute of Salt and Chinese Academy of Sciences Institute of Geology advanced experience, started in early 1976 the test. Seawater extraction of potassium salt water, in this regard, we have done some supplementary tests, such as zeolite exchange capacity test variant. As most of Yantian brine in our province did not extract potassium chloride, we did the test for extracting potassium from brine. In order to save coal, we use ammonium chloride as eluent
