钾盐浮选工艺中,常以脂肪胺类作为捕收剂。例如,浮选法生产工业氯化钾,用十八烷基胺作捕收剂。对产品,尾矿及中间过程进行脂肪胺量的监测工作,不仅有利于产品质量的提高,而且为综合利用及进一步提高工艺技术水平提供了必要的数据。Лурье等曾用苦味酸和曙红作试剂,测定浮选工业废水中所含 In the process of potassium salt flotation, fatty amines are often used as collectors. For example, the flotation process produces industrial potassium chloride with octadecylamine as a collector. The monitoring of fatty amine content of products, tailings and intermediate processes is not only conducive to the improvement of product quality, but also provides the necessary data for comprehensive utilization and further improvement of technological level. Лурье used picric acid and eosin as reagents, determination of flotation industrial wastewater contained
