In this work, a simple and inexpensive method has been developed to determine the amount of salt contained in a salted raw hide. Two different systems of analysis have been tested. In both methods, salt is removed by stirring the hide with deionized

This study examines the behavior of three different types of humic acids (natural humic acids, regenerated humic acids, and sulphited humic acids) with regard to their penetration and fixation to the leather. More specifically, through the tests carr

The aim of this study was to develop at pilot plant level two systems of pickle-tanning that would reduce both the amount of waste water and its content in chrome and chlorides while obtaining leathers that are commercially acceptable. In the first o
