摘要: Biosorption using agricultural wastes has been proven as a low cost and efficient way for wastewater treatment. Herein, grape peel treated by microwave- conventional-hydrothermal processes was used biosorbent to remove methylene blue (MB) from aqueous solutions. The adsorption parameters including the initial pH value, dosage of biosorbents, contact time, MB concentration were investigated find optimum conditions. obtained microwave-hydrothermal treatment only 3 min at 180 °C (microwave-hydrothermal peel, MGP) showed faster kinetics higher capability than that produced process (hydrothermal HGP) with duration time 16 h. maximum MGP under conditions (pH = 11, 2.50 g/L) determined Langmuir model reached 215.7 mg/g, which among best values achieved so far on biosorbents. These results demonstrated quick can be very promising organic dye removal
