Tarımsal atık üzerine malahit yeşili adsorpsiyonunda denge ve kinetik verilerin incelenmesi

Öz

Bu çalışmada yer fıstığı kabuğu üzerine malahit yeşili adsorpsiyonunda denge ve kinetik verilerin incelenmesi amaçlanmıştır. Yer fıstığının yüzey özelliklerinin belirlenmesi amacı ile XRD, SEM ve FTIR analizleri gerçekleştirilmiştir. Başlangıç malahit yeşili konsantrasyonu, adsorbent miktarı ve sıcaklığın adsorpsiyon verimi üzerine etkileri incelenmiştir. Langmuir izoterm modeli ve yalancı ikinci mertebe kinetik modelin yer fıstığı kabuğu üzerine malahit yeşili adsorpsiyonunun açıklanmasında en uygun modeller olduğu belirlenmiştir. Tarımsal atık ile malahit yeşili adsorpsiyonunda maksimum adsorplama kapasitesi 41.49 mg.g-1 olarak bulunmuştur.

Investigation of equilibrium and kinetic data in agricultural waste with malachite green adsorption

Abstract

In this study, it is aimed to investigate the equilibrium and kinetic data of the malachite green adsorption onto the peanut shell. XRD, SEM and FTIR analyzes were carried out by determining the surface properties of peanuts. The effects of initial malachite green concentration, adsorbent amount and temperature were evaluatedon the adsorption yield. The best fitting isotherm model was the Langmuir and kinetics model was pseudo-second order for malachite green adsorption onto peanut shell. Adsorption experiments showed that the maximum malachite green adsorption capacity of agricultural waste is 41.49 mg.g-1.
