迄今最快的测定皮革含铬量是用混合氧化剂(Na_2CO_3三份,K_2CO_3一份)熔融成灰的氧化法。这一方法所需的时间比较长(大约要7～8小时),同时需要各种不同的化学仪器,操作非常复杂;而且按此方法分析皮革仅仅是为了测定其标准度,不能作到预先了解其铬含量的情况。柯明捷尔娜皮革工厂实验室,采用快速的工作方法测定皮革中的铬含量。这个方法是在酸性状况下用溴酸钾来氧化铬,同时溴酸盐则转变成溴化物:
So far the fastest determination of chromium content in leather is mixed with oxidant (Na_2CO_3 three copies, K_2CO_3 a) melting ash ash oxidation. This method takes a long time (about 7 to 8 hours), at the same time require a variety of different chemical equipment, the operation is very complicated; and according to this method of analysis of leather is only for the determination of its standard, can not be made known in advance Its chromium content. Kemingtecer tanned leather factory laboratory, using fast working methods for determination of chromium in leather. This method uses chromium bromate to oxidize chromium in acidic conditions while bromate converts to bromide:
