在通常的工作条件下,不能对钨进行定量测定。本文叙述了我们通过实验,选用硫磺作热作热化学试剂,使钨在碳化前形成易挥发硫化物的办法消除钨的碳化作用,从而拟定了锡石中0.003-1.5％钨的直接光谱测定法。 Under normal operating conditions, tungsten can not be quantified. This article describes our experiment, the choice of sulfur as a hot chemical reagents, tungsten carbide before carbonization to form volatile sulfur compounds to eliminate the carbonation of tungsten, thereby formulating a caustic Stannous 0.003-1.5% tungsten spectrophotometry .
