RESUMO
0.999, the average recovery rates were 82%-88%, and RSD was not more than 4.3%(n=6), the detection limit was 0.05 mg/L. Conclusion The method is rapid, accurate, sensitive and applicable to determination of rhodamin B in water.
RESUMO
Glutaraldehyde is an important fine chemical product. As a disinfectant glutaraldehyde is used in the medical and public health area and also is widely used in the other areas. The content of the glutaraldehyde in the disinfectant products affects the efficiency directly. Determination of glutaraldehyde is important. Several determination methods of the glutaraldehyde were reviewed in this article.
RESUMO
Objective To established a method for determining the acetic acid peroxide in disinfectant. Methods The acetic acid peroxide determined by gas chromatography using FFAP fixative solution, Chromosorb W-AW DMCS column and FID detector. Results The detection limit was 0.001%.The linear range was from 0.01% to 25%.The recovery rate was 93%-102%?RSD was less than 2.93%. Conclusion The method is simple, rapid, sensitive and has a good selectivity. The sample can be directly detected without separation.
