The present study was aimed to experimental design optimization applied to removal of
malachite green (MG) from aqueous solution by ultrasound-assisted removal onto the gold
nanoparticles loaded on activated carbon (Au-NP-AC). This nanomaterial was characterized
using different techniques such as FESEM, TEM, BET, and UV–vis measurements. The
effects of variables such as pH, initial dye concentration, adsorbent dosage (g), temperature
and sonication time on MG removal were studied using central composite design (CCD) and …

The aim of the present study is experimental design optimization applied to the removal of
