Wastewater generated from industries consists of non-fixed dyes contributing to environmental pollution. Use of nanotechnology is being exploited for efficient degradation of dyes. Chromium sulphide nanoparticles have potential biological applications such as ion-selective membrane electrodes and probes for colocalization of membrane proteins. The biosynthesis of chromium sulphide nanoparticles by a high temperature hydrothermal approach has been reported herewith using chromium trioxide as the source of chromium and egg yolk (yellow) as the natural source of sulphur. Catalytic efficiency of chromium sulphide nanoparticles calcinated at 400 °C and 1000 °C has been tested for degradation of congo red, eosin Y, methylene blue as well as bromo cresol green of as prepared solutions and at acidic pH (pH 2.0).
