Abstract:

UV spect rophotometry is applied to the determination of terephthalic acid(TA),w ithout prior separationand masking reagent.The average recovery ratio of TA in sew age is 98.4 %.The results are satisfactoryand the method is simple, convenient and sensitive.

Key words: UV spectrophotometry, determination, terephthalic acid

摘要:

紫外分光光度法测定污水中对苯二甲酸,无需分离和加入掩蔽剂。测定线性范围 0 .8~ 2 0mg/L。对精对苯二甲酸生产装置排放污水进行测定,平均回收率为 98.4%。实验表明,在吸收光谱λ为 2 40nm处,废水中的醋酸、醋酸甲酯等不干扰测定,在 pH 7~ 9微碱性溶液中,溶液吸光度稳定,数值变化较小,此方法具有快速、简便、灵敏度高等特点。
