Item Prevention of Hydrosphere Contamination with Electroplating Solutions through Electromembrane Processes of Regeneration(Bentus, 2020) Сердюк, Василь Олексійович; Сердюк, Василий Алексеевич; Serdyuk, Vasil OleksIyovich; Склабінський, Всеволод Іванович; Склабинский, Всеволод Иванович; Sklabinskyi, Vsevolod Ivanovych; Большаніна, Світлана Борисівна; Большанина, Светлана Борисовна; Bolshanina, Svitlana Borysivna; Ableyev, A.; Диченко, Тетяна Василівна; Дыченко, Татьяна Васильевна; Dychenko, Tetiana VasylivnaThe work studies the process of Сd2+ and Zn2+ cations transfer through a RALEX®CM-PES 11–66 cation-exchange membrane and the cations reduction as metals on the cathodes at the cathode chambers of the electrochemical units with a view to prevent the hydrosphere contamination with the electroplating solutions. Electrolysis of the solutions that imitated the possible composition of the passivating baths contained 50 g/l sodium dichromate, 10 g/l sulfuric acid and impurity ions of Сd2+ and Zn2+ in various concentrations. The designed passivation solutions with certain amount of impurity ions in the colour solution were forcibly mixed. The impact of the impurity ions concentration in the colour solution and of a forced mixing on the metal reduction was studied. Regularity in the increased metal reduction dependent on the metal concentration was found and the conditions favouring the ion migration through the cation-exchange membrane due to forced mixing were defined.Item Harmful components of cosmetics(Sumy State University, 2016) Диченко, Тетяна Василівна; Дыченко, Татьяна Васильевна; Dychenko, Tetiana Vasylivna; Kolo, L.; Chibueze, M.There are various chemicals used in the preparation of cosmetics which should be used with caution, or else they can have harmful effects. Some of the more dangerous chemicals are described below.Item Deodorants and anti-perspirants(Sumy State University, 2016) Диченко, Тетяна Василівна; Дыченко, Татьяна Васильевна; Dychenko, Tetiana Vasylivna; Nwoke, S.A deodorant is a substance applied to the body to prevent body odor caused by the bacterial breakdown of perspiration in armpits, feet, and other areas of the body. A subgroup of deodorants, antiperspirants, affect odor as well as prevent sweating by affecting sweat glands. Deodorants are classified and regulated as cosmetics by the U.S. Food and Drug Administration (FDA) and are designed to eliminate odor. Deodorants are often alcohol-based. Alcohol initially stimulates sweating, but may also temporarily kill bacteria.Item Zamfara lead poisoning in Nigeria(Видавництво СумДУ, 2012) Диченко, Тетяна Василівна; Дыченко, Татьяна Васильевна; Dychenko, Tetiana Vasylivna; Mbah, C.S.; Adagba, S.E.Item Pollution problems associated with the disposal of plastics(Изд-во СумГУ, 2010) Диченко, Тетяна Василівна; Дыченко, Татьяна Васильевна; Dychenko, Tetiana Vasylivna; Чивуфа, Мвамба; Chyvufa, Mvamba
