目的对现有国标《游泳池水中尿素测定方法》进行适当的改进,以使尿素的检验更为准确、简捷、高效。方法按照GB/T18204.29-2000的方法对游泳池水进行检测,并对其中的检测步骤进行适当改进,对改进后的方法进行验证。结果改进后的检测方法无论从标准曲线的线性,显色反应稳定性,还是结果的准确度、精密度等都取得了满意的结果。结论经实验证明,改进后的国标方法在测游泳池水中尿素时,检验的效果更加明显,结果更加准确,值得推广。
Objective To improve the existing national standard method of determination of urea in swimming pool water to make the test of urea more accurate, simple and efficient. Methods According to the method of GB / T18204.29-2000, the swimming pool water was tested, and the testing steps in it were properly improved, and the improved method was verified. Results The improved detection method achieved satisfactory results in terms of the linearity of the standard curve, the stability of the color reaction, the accuracy of the results and the precision. Conclusion The experiment proved that the improved national standard method in the determination of urea in the swimming pool water, the test effect is more obvious, the result is more accurate, it is worth promoting.
