摘要
提出了脱硫灰中不同价态硫化物的测定方法,通过总硫量、亚硫酸盐和硫化物合量的测定,结合在二价铜盐存在下用水蒸汽蒸馏法,解决了各价态硫化物的测定。
A method of determining defferent valence sulfides in separated sulfer ash is presented and the problem of measuring them is solved with the measurement of the total sulfer content , the total content of sulf ide and sulf ateous salt and the use of the vapor distillation method in the presence of bivalence copper salt.
