Description
  • Leather manufacturing processes generate considerable amount of both solid and liquid waste. Especially chromium shavings represent potentially hazardous waste the processing of which is desirable not only from the economic, but particularly from the environmental point of view. To achieve the required quality of the resulting products it is crucial to remove some of the chemicals used during the treatment. The most important compound from this aspect is magnesium oxide (MgO). The most perspective method so far – extraction with diluted sulfuric acid – does not lead to total removal of MgO from the chromium cake. The contribution deals with the modeling of MgO extraction from chromium cake obtained by the filtration after alkaline hydrolysis of chromium shavings. We have studied in detail the conditions that could affect this technological procedure. The mechanism of the MgO extraction was studied through potentiometric titration and the kinetics data of the reaction of MgO with sulfuric acid within the given range of pH were obtained. Based on the experimental data, a mathematical model was proposed describing the extraction of MgO from chromium cake. The model will be further used as a tool for optimization of the extraction process.
