我們应用581型光电比色計和72型光电分光光度計对不銹鋼中铬、鎳、钛三种主要元素进行了試驗研究,鉻采用二苯基羰二肼比色法,钛采用对苯二酚比色法,鎳采用丁二肟比色法。經过几年的实际应用和多次的修改补充,得到了令人满意的結果。本文所述方法由于所得有色溶液均是紅色,适用于一般的国产光电比色計,无需特殊的仪器和試剂,操作簡便,对干扰物质均采用
We use the 581 photoelectric colorimeter and 72 photoelectric spectrophotometer stainless steel chromium, nickel, titanium three main elements were studied, chromium diphenylcarbazide colorimetry, titanium hydroquinone Colorimetric method, nickel dimethylglyoxime colorimetric method. After several years of practical application and multiple amendments to add, get satisfactory results. The method described herein due to the resulting colored solution is red, suitable for general domestic photoelectric colorimeter, without special instruments and reagents, easy to operate, the use of interfering substances
