Structural and adsorption behaviour of ZnO/aminated SWCNT-COOH for malachite green removal: Face-centred central composite design
Structural and adsorption behaviour of ZnO/aminated SWCNT-COOH for malachite green removal: Face-centred central composite design
In this study, an effective adsorbent was synthesized to remove malachite green (MG), which is one of the toxic dyes. Firstly, single walled carbon nanotube with carboxylated acid (SWCNT-COOH) was functionalized with diethylenetriamine and a new nanocomposite was obtained using nano zinc oxide (ZnO) powder. The effects of pH (3–7), the amount of adsorbent (5–15 mg) and the initial concentration (10–50 mg L–1) of the solution on the adsorption uptake were investigated. The optimal parameters that
