Zanieczyszczenie wody metalami ciężkimi stało się poważnym problemem środowiskowym, stwarzającym poważne zagrożenia dla zdrowia publicznego i gospodarki. W niniejszym badaniu mieszaninę proszku granitowego i marmurowego z Egiptu zmieszano w proporcji wagowej (2:1) i wykorzystano jako adsorbent do usuwania ołowiu i kadmu z roztworu wodnego. Przygotowany adsorbent scharakteryzowano za pomocą różnych technik, takich jak analiza dyfrakcji rentgenowskiej (XRD), skaningowa mikroskopia elektronowa z emisją polową (SEM, EDX), spektroskopia w podczerwieni z transformacją Fouriera (FTIR) oraz pomiar powierzchni właściwej. Adsorbent zaadsorbował maksymalnie 99,48% Pb2+ i 99,80% Cd2+. Wyniki wykazały, że adsorpcja Pb2+ i Cd2+ dobrze odpowiada izotermie adsorpcji Langmuira, podczas gdy badania kinetyczne wykazały zgodność z modelem drugiego rzędu. Optymalne parametry maksymalnego usuwania Pb2+ i Cd2+ na adsorbentach zastosowano do rzeczywistej próbki wody z laboratorium fabryki Kima, co wykazało wysoką skuteczność adsorpcji.
