Název v původním jazyce

Processing of Chrome Sludge Remained after Enzymatic Hydrolysis of Chrome Waste

Popis výsledku v původním jazyce

Enzymatic hydrolysis of chrome-tanned leather waste resolves the problem of processing solid wastes of the tanning and shoemaking industries. End products of enzymatic hydrolysis of a chrome cross-linked protein matrix are protein hydrolysate which is constantly finding new fields of application, and residual chrome sludge whose use is the subject of discussions. Its possible application in pigment manufacture is open due to quite high chromium content. On the other hand, requirements for its quality are such that direct employment in technologies of pigment manufacture is not possible without previous treatment. A particularly problematic issue is content of MgO which is used as promotor in enzymatic hydrolysis of chrome-tanned wastes. The presented work deals with possible isolation of magnesium from chrome sludge applying the method of 3-stage elution with water and adjusting pH, in which efficiency of up to 84% was reached.
