Present the results of study on the development of the technology for the recycling of hazardous waste of organosilicon production to produce grouting solution. It is shown that during hydrolytic esterification of bottoms from production of phenyltrichlorsilane is obtained product which can be used as a grouting solution to isolate the inflow of oilfield water. It is established that the quality of the product is affected by the ratio of reagents, chloride ion content, temperature and duration of polycondensation.
The possibility of using activated carbons in wastewater treatment from aromatic nitrophenols and nitrosulfonic acids was investigated. The main parameters of the adsorption process that provide the maximum degree of purification are determined: the amount of activated carbon and the pH of mother solutions. The method of regeneration of the extracted activated carbon by treatment with sodium hydroxide solution was studied, the optimal conditions of extraction were determined.
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.
