The opportunity of application of natural aluminosilicate – perlite – as reactive mineral admixture and as individual binding component when production of construction materials.
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 <0.01 mg/dm3; therefore, TMSP600 can be considered acceptable for treating sewage contaminated with vegetable oils at a low synthetic surfactant content in the system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
