Organic carbon is the main precipitant for uranium enrichment. 有机碳是铀的主要沉淀剂和富集剂;
The effects of three kinds of precipitants, i.e. salt, organic precipitant and PEG on the molecular packing are analyzed with 12 different crystal forms of T4 lysozyme and bovine pancreatic ribonuclease, where there is only one protein molecule in an asymmetric unit. 以不对称单位只有一个分子的牛胰核糖核酸酶和T4溶菌酶晶体为材料,着重研究了无机盐、有机溶剂和PEG三类不同的沉淀剂对晶体分子堆积的影响。
With the domestic and foreign advanced oxidizing preconditioning ( it can remove ammonia and nitrogen organic material, humic acid, magnesium and HVM film) separating technology, it separated solid precipitant from brine so as to obtain purified salt brine. 该工艺采用国内外先进的氧化预处理除氨氮有机物、腐植酸、镁和HVM膜分离技术将反应生成的固体沉淀物从卤水中分离出来,从而得到纯净的盐卤水。
