In the dissolved organic halogen (DOX) analytic test, prior to combustion, the granular activated carbon (GAC) on which the DOX is absorbed is washed with a sodium nitrate solution designed to remove any inorganic chloride that may have also adsorbed to the GAC. Thus, a potential positive interference is removed. This study investigated the effectiveness of the nitrate wash in eliminating possible interferences from bromide, bromate, and chlorate ions. No interference was detected from bromate or chlorate ion, but a small positive interference of about 12 micrograms Cl-/L per mg/L of bromide ion was found in the presence of background organic matter.
在溶解有机卤化物（DOX）分析测试中，在燃烧之前，将吸附有DOX的颗粒活性炭（GAC）用硝酸钠溶液洗涤，该溶液旨在去除可能也吸附在GAC上的任何无机氯化物。因此，消除了潜在的正干扰。本研究调查了硝酸盐洗涤在消除溴离子、溴酸根离子和氯酸根离子可能产生的干扰方面的有效性。未检测到溴酸根离子或氯酸根离子的干扰，但在存在背景有机物的情况下，发现每毫克/升溴离子有大约12微克Cl⁻/升的小正干扰。
