“…Approximately 10-15% of the total dyestuff is utilised or released into the natural environment aesthetically unfavourable, and these recalcitrant and coloured dye molecules are not so easy to degrade biologically and are resistant to degrade on exposure to water, to light and also to various chemicals [3,4]. Due to the toxic, carcinogenic, mutagenic and allergic nature of dyes, the direct discharge of untreated dye effluent can cause hazardous effects on living systems [5]. Several physicochemical and biological methods such as ozonation, chemical coagulation, chemical and electrochemical oxidation, photocatalysis, adsorption, and aerobic and anaerobic digestion are widely used Electronic supplementary material The online version of this article (https ://doi.org/10.1007/s4245 2-020-2603-9) contains supplementary material, which is available to authorized users.…”
