Development of a ghatti gum/poly (acrylic acid)/TiO hydrogel nanocomposite for malachite green adsorption from aqueous media: Statistical optimization using response surface methodology.

The primary goal of this study is to prepare and characterize a ghatti gum/poly(acrylic acid)/TiO (GG/poly(AA)/TiO) hydrogel nanocomposite for adsorption of the dye malachite green (MG) from the aqueous phase in a discontinuous system. A variety of approaches were used to investigate the structure, morphology, and thermomechanical characteristics of the synthesized hydrogel nanocomposite. Response surface methodology (RSM) was performed to analyze the impact of three processing parameters, namely adsorbent dosage, dye concentration, contact duration, and their interactions on MG dye adsorption capacity.
