在物相分析中,测定锑矿中的氧化锑(包括锑华Sb_2O_3和黄锑华Sb_2O_3·Sb_2O_5·nH_2O)常用2mol/L盐酸溶液室温浸取40min,或以1 mol/L酒石酸溶液室温浸取8—16h或在80—90℃热浸1h。以盐酸浸取,速度快,但有部分硫化锑也同时被浸出,影响结果的准确度。故一般认为以酒石酸溶液浸取较为合适。用容量法或比色法测定浸取液中的锑都较麻烦,往往需要分离干扰元素。极谱法虽然比较快速,但常常受到部分前还原元素的干扰。本法以酒石酸溶液浸取,直接用空气-乙炔火焰原子吸收法测定锑,得到了满意的
In the phase analysis, the determination of antimony oxide antimony (including antimony Sb 2 O 3 and antimony Huahua Sb 2 O 3 · Sb 2 O 5 · nH 2 O) commonly used 2mol / L hydrochloric acid solution for 40min leaching at room temperature or 1mol / L tartaric acid solution at room temperature leaching 8- 16h or hot dip at 80-90 ° C for 1h. Hydrochloric acid leaching, fast, but some antimony sulfide is also leached at the same time, affecting the accuracy of the results. It is generally believed that leaching tartaric acid solution is more appropriate. Volumetric method or colorimetric determination of antimony in the leaching solution are more troublesome, often need to separate interference elements. Polarographic method, although relatively fast, is often disturbed by the reduction of some of the former elements. In this method, tartaric acid solution is used for leaching, and the antimony is directly measured by air-acetylene flame atomic absorption spectrometry. Satisfactory
