Abstract

"Procedure for the concentration of solutions of sodium bichromate" which were obtained by reaction of sodium monochromate solutions with sulfuric acid, characterized in that sodium bichromate solutions contain up to 600 g/l Na2Cr2O7.2H2O and up to 300 g/l l of Na2SO4 are adjusted by adding concentrated sodium bichromate solutions to a content of more than 800 g/l of Na2Cr2O7.2H2O, wholly or partially separating the precipitated sodium sulphate or leaving it in the liquid and the solutions or suspensions thus obtained concentrate in a multi-step evaporator.
