Для удаления остаточных количеств фармацевтических соединений, присутствующих в питьевой воде, на всех этапах водоподготовки могут применяться разнообразные способы очистки, основанные на различных физико-химических принципах. В работе приведены результаты экспериментального исследования эффективности удаления с помощью бытовой стационарной системы водоочистки остаточных количеств фармацевтических препаратов – антибиотика левомицетина (хлорамфеникола) и стероидного гормона эстрона – из модельного раствора, приготовленного на основе водопроводной воды с добавлением лекарственных препаратов. Показано, что бытовая система водоочистки обладает способностью существенно снижать остаточные концентрации фармацевтических препаратов левомицетина и эстрона на всем протяжении заявленного производителем ресурса. В секторе бытовой водоочистки установки адсорбционного типа по-прежнему остаются наиболее востребованным типом водоочистных систем, обеспечивающих высокую эффективность удаления различных загрязнителей при минимальных капитальных затратах. To remove residual amounts of pharmaceutical compounds present in drinking water, a variety of purification methods based on various physicochemical principles can be used at all stages of water treatment. The paper presents the results of an experimental study of the efficiency of removing residual concentrations of pharmaceuticals – laevomycetin antibiotic (chloramphenicol) and estrone steroid hormone – from a model solution prepared on the basis of tap water with the addition of drugs, using a home fixed water purification system. It is shown that the home water purification system provides for the significant reduction of residual concentrations of chloramphenicol and estrone throughout the service life declared by the manufacturer. In the household water purification sector, adsorption-type units are still the most in-demand type of water purification systems that provide for the high efficiency in removing various pollutants with minimal capital costs.
