Abstract
Inventia se refera la obtinerea unor complecsi de aluminiu-crom, sub forma de solutie sau pulbere, care contin 60% Al indice 2 O indice 3 si 40% Cr indice 2 O indice 3 si au o bazicitate de 33%, care pot fi folositi la tabacirea si retabacirea pieilor. Utilizarea acestor complecsi în tabacarii duce la reducerea consumului de crom, acid sulfuric si glucoza si la reducerea însemnata a gradului de poluare cu crom a deseurilor apelor reziduale si namolurilor rezultate din întreprinderile de pielarie.The invention relates to the production of aluminum-chromium complexes in the form of a solution or powder containing 60% of an index of 2 an index of 3 and of 40% of Cr of index 2 of an index 3 having a basicity of 33% which can be used to tanning and skin rejuvenation. The use of these complexes in tanning leads to reduced consumption of chromium, sulfuric acid and glucose and to a significant reduction in the degree of chromium pollution of tailings and sludge from leather enterprises.
