- •
ZnS: Mn-NPs-AC were used for the simultaneous removal of dyes from aqueous solution.
- •
Derivative spectrophotometric method for resolve of spectra overlap of MG and MB.
- •
Dyes removal significantly were accelerated under application of ultrasound.
- •
Response surface methodology was used to optimize the process variables.
- •
The MB and MG adsorption data were best followed by Langmuir and pseudo-second order models.
