Rhodium and iridium separation is one of the most troublesome problems of the noble metal separation and purification previously the platinum group metals, previously vulcanized separation separation at 80 degrees, often rhodium and iridium co-precipitated or co-solvent, but occurs proportionally changes, the condition is difficult to control, so that the final yield is low quality, rhodium and iridium straight! occurs only from solvent extraction of rhodium and iridium separation step is no longer a myth, especially synthetic trialkyl phosphine oxide (in TRPO) separation of the rhodium and iridium It is one step at a time, such as the direct yield of ion exchange enthalpy is above 93%, and can be mentioned 99.96% purity, 铱 can mention 99.90% purity! So solvent extraction will become the classic of cesium separation Mainstream! Hubei ruiyate Automobile Co.,Ltd , https://www.nbruiyate-automobile.com
