摘要：

Dragon fruit foliage in its natural form was applied for decolorization of methyleneblue, a cationic dye from aqueous solution. The effects of major parameters like initial dye concentration, pH, adsorbent dose, temperature and contact time were investigated in batch experimental set-up. The optimum values for removal of methylene blue were identified to be pH 9.0 with 30 hours contact time using 1.2 g L-1 biosorbent dosage at 250mg L-1 initial dye concentration. The present results suggested that foliage of dragon fruit can be a potential agricultural byproduct to be used as an environmental friendly and low cost biosorbent.
