ТИОМОЧЕВИНА ИШЛАБ ЧИҚАРИШДАГИ МЕЛАМИНСАҚЛОВЧИ ЧИҚИНДИ, ТОЗАЛАШ, ҚАЙТА ИШЛАШ ВА ҚЎЛЛАШ
##submission.downloads##
Тиокарбамид ишлаб чиқариш чиқиндилари асосида ион алмашиниш хусусиятига эга янги маҳсулотлар олинди. Аниқланишича, таркибида меламин бўлган чиқиндиларни карбамид-формалдегид смоласи билан конденсатлаш ва иссиқлик билан ишлов бериш натижасида меламин, тиокарбамид ва дисияндиамиднинг амин ҳосилалари олиниб, ион алмашинувчи сифатида синовдан ўтказилди. Таҳлилнинг кимёвий усулларидан фойдаланиб, олинган маҳсулотларнинг тузилиши ва хоссалари ўрганилди. Олинган ион алмашинувчининг кинетик характеристикалари диффузия тенгламалари ёрдамида ўрганилди.
