Treatment of Textile Dye Reactive Orange HE2R by using BIR Oadsorbent Azospirillum and Tricoderma

Adsorption of reactive orange HE2R dye from an aqueous solution by using low cost biofertilizers such as Azospirillum and Trichoderma was studied. The study comprises of assessment of adsorption capacities with respect to adsorbent dosages, dye concentration, pH, contact time, and dye solution temperature. The Langmuir adsorption isotherm effectively associated with the experimental data, and the isotherm parameters, Qmax and R2 was computed. For Azospirillium and Trichoderma, the adsorption capacities were 146.0765199 mg/g and 124.0509789 mg/g respectively. Using the Langmuir isotherm, a single-stage batch adsorber was designed for various ratios of treated dye volume to adsorbent mass
