Abstract: 
Органічні речовини у фосфоритах були предметом численних досліджень. Оцінювання і вирішення деяких проб¬лем, таких як забруднення, що виникають під час промислового виробництва фосфорної кислоти, cтановлять великий інтерес і дозволяють отримати кращі виходи фосфорної кислоти. Тверді відкладення, що утворюються під час виробництва фосфорної кислоти екстракційним способом, були охарактеризовані, і в них виявили маладрит, гіпс, сліди металів і наявність органічних речовин. Ідентифікацію органічних речовин проводили в зразках забруднення за допомогою ІЧ- та раман-спектроскопії. Кількісне визначення загального вмісту органічних речовин у зразках забруднень здійснено за допомогою методів Воклі-Блека та кальцинування. Знання про вміст органічних речовин у шарах забруднення дає змогу краще зрозуміти явища в процесах.
