Auramine yellow dye used in textile industry was treated with different quantities of carbon activated dried orange peel for ten days. 0.2, 0.4, 0.6 and 0.8 g quantities of orange peel were tested with 100, 200, 300 and 400 ppm of auramine yellow dye. Increase in orange peel quantity and treatment period caused an increase in the activity of decolourization. Decolourization was the maximum at pH2. Orange peel of 0.6 g quantity performed better and the isotherm models could explain the biosorption process.

橙皮在纺织工业中使用的商品金胺黄色染料脱色中的功效

用不同数量的活性炭干燥橙皮处理纺织工业中使用的金胺黄色染料十天。用100、200、300和400 ppm的金胺黄色染料测试了0.2、0.4、0.6和0.8 g量的桔皮。桔皮数量和处理时间的增加导致脱色活性的增加。在pH2时脱色最大。0.6 g量的桔皮效果更好，等温线模型可以解释其生物吸附过程。
