人们对于络合剂这种具有很独特的和普遍性质的化合物早已产生了兴趣。这些化合物在无机分析中的应用,推动着高选择性的和灵敏试剂的合成和探索方面工作的发展。近来,对络合剂的兴趣剧增,这类药剂在复杂的稀有金属和有色金属矿物的浮选领域中 There has long been interest in complexing compounds of a very unique and universal nature. The use of these compounds in inorganic analysis has driven the development of work on the synthesis and discovery of highly selective and sensitive reagents. Interest in complexing agents has skyrocketed recently and these agents have been used in the complex field of flotation of rare and non-ferrous minerals
