我们开发了一种选择性和可重复使用的化学发光测试条来测定次氯酸盐。次氯酸盐敏感测试条包含一个10mm × 9mm的阴离子纤维素纸，荧光循环，粘在10mm × 4cm × 0.5 mm的聚酯条上。当将1ml样品注入含有该条带的常规细胞时，在光度计中测量化学发光，可以测定次氯酸盐。调整了膜的组成和反应条件，以获得足够的灵敏度和选择性。次氯酸盐在2.0 ~ 10.3 mg L-1和10.3 ~ 51.4 mg L-1两个线性范围内呈线性响应，检出限为0.4 mg L-1。同一一次性试纸在中等水平上的重复性为6.6%。为相对标准偏差（rsd），使用不同试纸时为12.3%。该方法适用于不同水质中次氯酸盐的测定。(C) 2004 Elsevier B.V.版权所有
We have developed a selective and reusable chemiluminescent test strip to determine hypochlorite. The hypochlorite-sensitive test strip contains a 10 mm x 9 mm piece of anionic cellulose paper in fluoresceinate cycle, glued to a 10 mm x 4 cm x 0.5 mm polyester strip. The measurement of the chemiluminescence in a luminometer when 1 ml of sample is injected into a conventional cell containing the strip makes it possible to determine hypochlorite. The composition of the membrane and reaction conditions have been adjusted to obtain adequate sensitivity and selectivity. The test strip responded linearly to hypochlorite over two linear ranges, the first 2.0-10.3 mg L-1 and the second 10.3-51.4 mg L-1, with a detection limit of 0.4 mg L-1. The reproducibility using the same disposable test strip at a medium level of the range was 6.6%. as relative standard deviation (R.S.D.), and 12.3% using different test strips. The procedure was applied to the determination of hypochlorite in different types of waters. (C) 2004 Elsevier B.V. All rights reserved.
