AbolishedWorkplace air--Determination of chromium trioxide，chromates and dichromates--Diphenylcarbazide spectrophotometric method
车间空气中三氧化铬、铬酸盐、重铬酸盐的二苯碳酰二肼分光光度测定方法
Application Summary AI generated
This standard specifies a diphenylcarbazide spectrophotometric method for determining concentrations of chromium trioxide, chromates, and dichromates in workplace air. It is applied in industrial hygiene monitoring and occupational safety assessments, particularly in facilities such as electroplating plants, pigment manufacturing, and metal finishing operations where airborne hexavalent chromium compounds pose inhalation risks. The method enables compliance with workplace exposure limits by providing a quantitative analysis of these carcinogenic substances in air samples.
