摘要
通过实验,证明了硫氰酸汞分光光度法测定空气中氯化氢空白值偏高的主要原因,是由于两种显色剂之间相互反应引起的。因此,在测定过程中,显色剂的加入量必须十分准确。
Through the experiment , this article had proven that higher blank value of hydrogen chloride in air by mercuric thiocyanide spectrophotometric method is caused by the reaction of two kinds of developer. Thus, in the determination process, the volume of developer added has to be extremely accurate.
