Résumé : |
Due to effluent limitations there is a great deal of interest in the tanning industry to find a replacement for ammonium salts currently used in the deliming process. Considerable attention has been paid to magnesium salts, in particular to magnesium sulfate or magnesium chloride, either as the salt alone or in combination with various acids. Leather resulting from deliming with these magnesium salts is comparable and in some ways superior to leathers delimed with ammonium sulfate. This paper proposes the use of magnesium lactate for non-ammonia deliming of white hides. Magnesium lactate combines the advantages of deliming with lactic acid (increased solubility over the calcium salt of the acid) and the advantages of magnesium salts (improved grain quality of the finished leather). The detailed procedures and the results of tannery scale evaluations using magnesium lactate are presented. An inexpensive source of this chimical is described, prepared from a dairy industry waste effluent. |
