将PH值调节到3.5左右以降低弱酸的电离，并由此降低了弱酸的阴离子干扰。
The PH value is buffered close to 3.5 which depress ionization of weak acid and, thus, interference from their anions.
为了消除潜在的干扰物质，可在一个SPE阴离子交换柱上进一步清洗样品。
In order to remove potentially interfering substances, the sample can be further cleaned on an SPE anion exchange cartridge.
采用碱性亚甲蓝萃取去除蛋白质、硫化物等干扰，然后经酸性亚甲蓝萃取法分析未经处理或仅简单处理生活污水中的阴离子表面活性剂浓度。
The interferences of protein and sulfide in the domestic wastewater are extracted with alkaline methyleneblue, and then the concentration of anionic surfactant is detected by using acid methyleneblue.
由于铀溶液中的硝酸根对阴离子交换树脂具有较强的亲合力，相当低的硝酸根就足以干扰硫酸铀酰离子的吸附。
Nitrate of low concentration can interfere with adsorption of uranyl sulfate anion on anion-exchange resins because the anion-exchange resins have a stronger affinity for nitrate in uranium solution.
