Chromium centrifugal extraction machine extraction separation and sulfuric acid
Chromium centrifugal extraction machine extraction separation and sulfate in chromate production waste water, waste and chromium plating industrial importance, there are two types of extractant can be used for chromium centrifugal extraction machine extraction separation and sulfuric acid, namely the neutral phosphate like the TBP and amine.
The TBP extraction priority chromium, undiluted the TBP from 1 kmol/m3 can load 6 - in sulfuric acid solution
7 kg/m3, chromium, and from 2 kmol/m3 in sulfuric acid solution can be increased to 55 kg/m3 of chromium, chromium sulfate in preference to amine extraction, so while chromium in dilute acid solution has good extraction performance, but with the increase of concentration of sulfuric acid extraction ability decline.
The image below for centrifugal extraction machine the relationship between the extraction separation of chromium and sulfuric acid.
