- Chromium(III) sulfate usually refers to the
inorganic compound with the formula Cr2(SO4)3 • 12(H2O).
- Chrome Sulphate is the basic tanning chemical.
- Apart from being expensive, Chrome Sulphate is
also a serious pollutant.
- Finishing chemicals are used to impart certain
properties to
the leather like softness, color, appearance etc.
- Like tanning chemicals finishing chemical also
get discharged into wastewater.
- Only those chemicals are fully retained which are
applied as surface coating.
- Basic chromium sulfate is produced from chromate
salts by reduction with sulfur dioxide.
- The collected data shows 50-150 liter water is
used for
conversion of one kg of raw skin into leather.
- The removal of Cr(III) from wastewater using CHT
is a
good alternative because the oxidation of Cr(III) to Cr(VI) it is
not necessary due to the characteristics of the processes.
- In tanning process water is used as carrier to
facilitate different chemical reactions and after completion of
process the water leaves the system as wastewater
in the same quantity as added to the system.
- The main application is making chrome tanned
leather, insolubilizing protiens and other organic substances.
- Chrome recovery and reuse process, besides the
elimination of environmental concerns related to chrome, has also
economic benefits to the tanners as the chromium discharged as
effluent component as claimed Tanners Association, can be 100 %
recovered . The recovery cost has been reported to be about 30% of
the fresh chromium cost
