- •
A series of acid dyes has been synthesized from 1-(p-sulphophenyl)-3-methyl-4-amino pyrazolone with different phenol derivatives at high temperature 25–35°C and their Fe (II) and Cu (II) complexes have been accomplished at temperature 60–65°C.
- •
Investigated acid dyes have been applied on leather which exhibit high light fastness, wash fastness and rubbing fastness.
- •
Exhaustion and fixation values of these synthesized dyes are very high due to elevated physical as well as chemical interactions of polar groups with collagen protein of leather.
- •
Nanoscale ZnS/TiO2 composite was synthesized and characterized.
- •
The prepared photocatalyst was used for the removal of Acid Blue 113 dye.
- •
The process was optimized and analyzed using central composite design.
- •
A high AB113 dye removal (99.0%) was obtained at the optimal conditions.
