Noniyonik Igepal CA-630’un adsorpsiyonunda Zonguldak bitümlü kömürü ve Sivas Divriği Uluçayır (SDU) linyiti adsorplayıcı olarak seçilmiştir. Kinetik ve denge çalışmaları 3-50 ppm başlangıç derişiminde 24 saat süreyle gerçekleştirilmiştir. Düşük çalkalama hızında Igepal CA-630 adsorpsiyonu artmıştır. Sıcaklık artışı SDU linyitinde adsorplanan madde miktarının artmasına, Zonguldak bitümlü kömüründe ise azalmaya neden olmuştur. Kömürlerin adsorpsiyon kapasiteleri kömürlerin parçacık boyutunun azalmasıyla artmıştır. Zonguldak bitümlü kömürüne pH’ın etkisi, ortamın pH’ı 0,1 N H2SO4 ile 9,10’dan 3,08’e düşürülerek incelenmiştir. Zonguldak bitümlü kömürüne adsorplanan madde miktarı pH’ın azalmasıyla artmıştır. Yağ aglomerasyon tekniği ile minerali giderilmiş Zonguldak bitümlü kömürüne adsorplanan madde miktarı Zonguldak bitümlü kömürününden daha az olmuştur. Adsorpsiyon verilerinin Freundlich izotermine daha fazla uyum gösterdiği ve termodinamik parametre sonuçlardan adsorpsiyonun ekzotermik ve kendiliğinden olduğu görülmüştür.
