Bromlu uçucu organik bileşikler toprakta çevre problemi yaratan kirleticilerdir. Bu çalışmada etilbromürünkaolin ve toprak tabletlerindeki adsorpsiyonu tek taraflı tek tablet moment tekniğiyle incelenmiştir. Kaolin vetoprak tabletlerinde etilbromürün sıfırıncı momentlerinin analizinde tersinir adsorpsiyon gözlenmiştir. Gözeneklikatılarda etilbromürün adsorpsiyon denge sabitleri puls tepki deneyleri için türetilen birinci mutlak momentifadelerinin kullanılmasıyla hesaplanmıştır. Toprak ve kaolin tabletlerinde etilbromürün adsorpsiyon dengesabitleri (ρpKi) sırasıyla 3,81 ve 1,68 olarak bulunmuştur. Toprak tabletinde etilbromürün adsorpsiyon dengesabiti kaolin tabletindekine göre daha büyük çıkmıştır.
