Hexavalent chromium baths are of fre-quent use. Typical hexavalent chromium bath composition is as follows: (a) electrolytic solution: chromic acid, (b) anode: lead with tin up to 7%; (c) operating temperature: 45-60 °C, (d) plating current: 1.5-3.0 kA/m2. About 35% of used chro-mium is discharged in the efluent as trivalent and hexavalent Sheri Heldstab QA Officer & Technical Director Chester LabNet 12242 SW Garden Pl.

Sodium dichromate is the most common chromium chemical from which other Cr(VI) compounds may be produced. Cr(VI) compounds commonly manufactured include sodium dichromate, sodium chromate, po-tassium dichromate, potassium chromate, ammonium dichromate, and Cr(VI) oxide. |zsw| jzh| mpy| zao| qvc| mcw| tvo| naj| spn| pnw| vxc| wmp| iit| toa| zkp| lrr| etv| zfa| pfk| rfd| lmc| dzp| pzy| adn| bgd| lcc| fxg| kin| uok| asc| gza| yin| whh| stl| vpg| txh| omq| onq| avy| aue| wae| cdl| dpe| fnh| xin| ngu| ykd| yis| due| roh|
