| Abstract: | In this paper ,the waste water of chromic acid is studied,which is used as a hardening liquior on electro-nic shadow mask. The concentration of chrome is detected by the spec-trophotography and iodimetry. The recovered water is used as a tanning liquor after the treatments such as decontami-nation, purification, reduction and compound. The percent recovery of Cr 6 is 98.8%,at the same time,the indexs of tanned leather reached to the national standard. |
