摘要
介绍了在λ＝２０５ｎｍ处，以水为参比，用石英比色皿，在紫外分光光度计上测磷化液中ＮＯ３－的含量可得到较满意的结果。
The article introduces that taking the water as reference and using quartz colorimetric utensil to measure No3- content in phosphatization liquid with ultraviolet ray spectrophotometer at where λ is equal to 205nm can get satisfactory result.
