MONITORING AND OPTIMISATION OF CHROMIUM UPTAKE IN TANNING PROCESS IN LEATHER MANUFACTURE BY USING SPECTROPHOTOMETRY
Published: 29 Jul 2017
Abstract: In the present study leather samples have been tanned with various application times of temperature and basification; and chromium exhaustion of the process has been monitored by measuring the chromium concentration of the float with a spectrophotometer in short time intervals (5 -10 minutes). Optimal conditions of chromium tannage have been tried to be determined by comparing the data obtained from graphics and results of the physical tests and chemical analysis applied to the leather samples. Consequently, online monitoring of chromium process by using spectrophotometric measurements can be used in chromium tanning process in leather manufacturing for efficient process control and optimization.
