摘要：Textile wastewater contains many organic and inorganic pollutants and discharging them into received waters leads to serious environmental problems. In this study, rose watering waste ( Rosa damascena ) was used as an abundant and available material for reduction of Chemical Oxygen Demand (COD) and color from textile wastewater in Kashan (Iran). So, rose watering wastes as powder in both bulk and nanometric states were examined and characterized using Scanning Electron Microscope (SEM). The effect of various parameters including contact time (15, 30, 45, 60, 75 and 90 min), pH (3.0, 5.0, 7.0 and 9.0) and nano-biosorbent dosage (500, 1000, 2000 and 4000 mg L1) on filtered wastewater were investigated. Also, biosorption kinetics for COD was evaluated.
