Contents on the CD Romhydochloric-acid-2

  • 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
