•A novel ultrasound-assisted/nanoparticle adsorption as an efficient dye removal.•Nanoparticles shows considerable advantages on the removal yield of dyes.•The usability of SnS-NP-AC for the removal of erythrosine was investigated.•Ultrasound shows considerable advantages on the removal yield of dyes.•The effects of variables were studied using experimental design based response surface. A novel ultrasound assisted adsorption protocol for the removal of erythrosine from aqueous solution by tin sulfide nanoparticle loaded on activated carbon (SnS-NP-AC) has been described. The main and interaction of variables (pH, sonication time, adsorbent dosage and initial dyes concentrations) on the removal of erythrosine were studied and optimized by a central composite design (CCD) combined with response surface methodology (RSM). The small amount of proposed adsorbent (0.02g) is applicable for removal of high content of erythrosine with high removal percentage (>98%) in short time (4.5min). Application of ultrasound led to remarkable decrease in adsorption time.
