摘要
本文比较了两装置测定砷的效果。实验结果表明：测定的准确度和精密度以及装置的结构性能和使用性能，丘氏定砷器均优于国家标准ＧＢ７４８５－８７规定的装置，应用于废水中砷的测定，结果满意。
In this paper, the effect of Qiu's Arsenic Analyzerwas compared with apparatus of national Standard Method of China(GB-7485-87). The experimental results show that Qiu's Arsenic Analyzer is much better than the latter. It has good accuract and precision .In addition, it has also following advantages: 1. The new apparatus is durable, secure and com-pact in structure. 2. 1t is convenient for use. 3. 1t is more convenient to cleanse the absorbing tube than that ofother apparatus.
