The objective of this study was to assess the suitability and efficiency of Zinc Hydroxide nanoparticle loaded on activated carbon (Zn(OH)2-NP-AC) for the removal of Brilliant green (BG) in batch method was studied. The influence of variable including pH, contact time, initial dye concentration, Zn(oH)2-NP-AC amount, temperature, etc by one at time optimization method has been investigated. BG contents and its removal percentage were determined using a UV-Vis spectrophotometer before and after adsorption. The sorption processes followed the pseudo-second-order in addition to intraparticle diffusion kinetics models with good correlation coefficient. Equilibrium data fitted well with the Langmuir models with maximum Langmuir adsorption capacity of 100 mg/g.
