Abstract

A possibility of the separation of trace amounts of arsenic and antimony and macroquantities iron, chromium, molybdenum, and tungsten by the precipitation of the latter was investigated; regularities of the coprecipitation of arsenic and antimony are studied. The coprecipitation of arsenic and antimony in the precipitation of iron, chromium, molybdenum, and tungsten can be inhibited by introducing a certain amount of hydrofluoric acid. This decreases the specific surface and porosity of the precipitates and inhibits the coprecipitation process. A method is developed for the simultaneous determination of arsenic and antimony in alloy steels by inductively coupled plasma atomic emission spectrometry with preliminary separation of the main components of iron, chromium, molybdenum, and tungsten.

合金钢中砷和锑的测定中铁,铬,钼和钨的沉淀程序

摘要

研究了通过沉淀分离出痕量的砷,锑和大量铁,铬,钼和钨的可能性;研究了砷和锑共沉淀的规律。通过引入一定量的氢氟酸,可以抑制砷和锑在铁,铬,钼和钨的沉淀中的共沉淀。这降低了沉淀物的比表面积和孔隙率,并抑制了共沉淀过程。开发了一种通过电感耦合等离子体原子发射光谱法同时分离铁,铬,钼和钨的主要成分的同时测定合金钢中砷和锑的方法。
