Cr6+ is widely applied in automotive metal coating and leather, Cr6+ test is an indispensable index for the test of prohibited substances on automobiles. In order to test Cr6+ content in the metal coating of automotive materials, a rapid semi-quantitative detection procedure was established by the test strip method. Compared with ultraviolet method and point test method in QC/T 942—2021 Test Methods of Hexavalent Chromium in Automotive Materials, results of the strip test method are basically consistent with traditional qualitative and quantitative test methods. The advantage of strip test method is that the test can be completed within 5 minutes, far less than that of the traditional method that takes 4 to 8 hours. Meanwhile, operation of the test is simple, which saves large amount of test consumables and reduces waste discharge.
