Název v původním jazyce

Washing of MgO from chrome sludge in an acidic environment

Popis výsledku v původním jazyce

Chrome sludge is a solid residue remained after enzyme hydrolysis of leather shavings. The chrome sludge contains chromium, magnesium oxide, and residual protein. MgO was used as a promoter in enzyme hydrolysis of leather shavings. For further processing(e.g. in a pigment manufacture) the chrome sludge has to be depleted of undesirable components, protein and MgO. Presented work deals with washing of MgO from the chrome sludge in an acidic environment running in two stages. Firstly, washing of the chrome sludge with water to the purpose of removing unbound MgO, and secondly, washing of the chrome sludge with diluted sulphuric acid (pH = 6) to the purpose of removing bound MgO. Total efficiency of two-stage washing-out of magnesium oxide from the chrome sludge is nearly 79% (related to starting content of MgO in the chrome sludge).
