Bu çalışmada,
önceki çalışmamızda ZnCI₂ aktifleştiricisi kullanılarak kimyasal
aktivasyon yöntemi ile iğde çekirdeğinden elde edilen 1836 m²/g BET
yüzey alanına sahip aktif karbon kullanılarak sulu çözeltilerden Pb(II)
adsorpsiyonu incelenmiştir. Bu amaçla, çözelti pH’ı, aktif karbon miktarı,
çözelti başlangıç derişimi ve işlem sıcaklığı parametrelerinin Pb(II)
adsorpsiyonuna etkileri ayrı ayrı incelenmiştir. Artan sıcaklık ve aktif karbon
miktarı ile Pb(II) giderim yüzdesinin arttığı belirlenmiştir. Adsorpsiyon denge
verilerinin Langmuir izotermine uyduğu tespit edilmiş olup, maksimum
adsorpsiyon kapasitesi (q_maks) çözelti başlangıç pH değeri pH=4’de
86,207 mg.g^-1 olarak bulunmuştur. Sulu çözeltiden Pb(II) adsorpsiyon
kinetiğinin Elovich kinetik model ile uyumlu olduğu tespit edilmiştir. Partikül
içi difüzyon modeli sonuçlarına göre adsorpsiyon işleminin birden fazla
basamakta gerçekleştiği ve difüzyonu kontrol eden basamağın en küçük difüzyon
katsayısına (1,455) sahip olan 3. basamak olduğu belirlenmiştir.
