- Abstract
- Results of neutralization of low concentrated solutions of chromic acid by means of hydrazine are represented. Rise in temperature essentially accelerates process of neutralization of the washing water containing Cr(VI)-compounds. Using the hydrazine salts also for reduction of Cr(VI)-compounds is offered.
