一种用酸碱改性的多孔氮化硼从纺织工业废水中去除脂肪酸的方法
摘要：
本发明涉及一种用多孔氮化硼从纺织工业废水中去除脂肪酸的方法，使用酸碱改性多孔氮化硼吸附纺织废水中的脂肪酸。其中酸改性应用2％硝酸或2％柠檬酸或混合酸进行，碱则利用2％氢氧化钠或2％氢氧化钙或2％氨水改性。该方法适用范围广，可吸附浓度0.15-0.2mg/L，pH2-7，温度25-55℃环境内的纺织废水脂肪酸，且吸附率均可达到79％以上。其操作简单，可再生性高。在纺织废水处理方面十分可行。
摘要（英）：

The invention relates to a method for removing fatty acid from textile industry wastewater by using porous boron nitride. Acid-base modified porous boron nitride is used for adsorbing fatty acid in the textile industry wastewater, wherein acid modification is carried out by using 2% nitric acid or 2% citric acid or a mixed acid, and alkali modification is carried out by using 2% sodium hydroxide or 2% calcium hydroxide or 2% ammonia water. The method is wide in application range, fatty acid in textile wastewater with a concentration of 0.15-0.2 mg/L and a pH of 2-7 in an environment with a temperature of 25-55 DEG C can be adsorbed, and the adsorption rate can reach 79% or above. The method is simple to operate and high in renewability, and is very feasible in textile wastewater treatment.
