Bu çalışmada glutaraldehitle
çapraz bağlanmış kitosan kaplamalı muz kabuğu (KMK) performansı, sulu
çözeltilerden Cr (VI) iyonlarının adsorpsiyonu ile araştırılmıştır. Farklı
deneysel parametrelerin; Cr (VI) iyonlarının farklı konsantrasyonu, pH,
adsorban miktarı ve temas süresinin etkileri değerlendirilmiştir. Metal analizi UV-Vis. cihazı ile
gerçekleştirilmiştir.  (KMK)
boncuklarıyla Cr(VI) adsorpsiyonunda optimum pH değeri 2.0 olarak bulunmuştur.
(KMK) kullanılarak Cr(VI) maksimum giderimleri, pH 2, temas süresi 1
saatte,  % 90,2 olarak elde edilmiştir.
Çeşitli fonksiyonel gruplar FTIR analiziyle tanımlanmıştır. Adsorpsiyon deneyi
denge verilerinin Langmuir modeline daha uygundur. (KMK) için Cr(VI) maksimum
adsorpsiyon kapasitesi 102 mg/g olarak bulunmuştur. Sonuçlar, Cr(VI)
iyonlarının adsorpsiyonu için (KMK)’nın uygun adsorban olduğunu göstermiştir.
