| Résumé : |
In the absence of an effective method of treating soak liquor containing sodium chloride, an alternative curing technique for hides and skins using phenol-borax mixture is discussed. The characterization of spent liquor, first soak liquor and second soak liquor is reported. Anaerobic treatment of phenolic waste liquor does not yield the desired results, but treatment with hydrogen peroxide and a catalyst produced good results. The optimum conditions like pH, phenol : H2O ratio, the catalyst (FeSO4, 7 H2O) and phenol concentrations have been arrived at for the maximum removal of phenol. The residual phenol, after treatment with hydrogen peroxide, can be successfully removed using lime under agitation. |
