The Fe-doped NPs were synthesized by decomposing copper(ii) N,N-diphenylmethylpiperazinecarbamodithioate via a facile single-step, one-pot solvothermal method in the presence of iron salt. The Cr^VI photoreduction data were fit to a pseudo-first-order kinetic model and a Langmuir model. The CuS/Cu₂S NP reduction ability for Cr^VI increases with an increase in dopant percentage. The best catalyst (9% Fe-doped) was able to reduce Cr^VI (10^-4 M K₂Cr₂O₇) to Cr^III in raw water using an initial amount of 10 mg in 6 min with a reduction efficiency of up to 100%. The photocatalytic activity was examined while varying five different parameters: sunlight, diffused light, change in pH, and changes in the concentration of the catalyst and the temperature. This new approach presents an active, simple, and cost-effective means for wastewater treatment.
