Description
Summary:The peculiarities of sorption interactions between TMSP600 material obtained from carbonate sludge from sugar production and model sewage containing vegetable oils are investigated. It was found that in the absence of synthetic surfactants, TMSP effectively interacts with emulsions of vegetable oils and causes their rapid clarification. In the presence of sodium lauryl sulfate, efficiency is markedly reduced. The observed phenomenon is explained by the presence of a negative charge on the oil droplets, as a result of which they are repulsed from TMSP600 particles. The purification efficiency remains quite high at a synthetic surfactant concentration of
