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.
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.
