【Abstract】 In order to supervise whether the effective component of disinfectants is in coincidence with the actual content reported for sanitation consent and check whether the disinfectiants sold in the market are qualified,we made this investigation. Dual wavelength violet spectrophotography was used to determine the content of glutaral and benzalkonium chloride in disinfectant sample. The minimum detectable concentration of glutaral and benzalkonium chloride is 0 02% and 0 002%, respectively. [Conclusion] The method was verified and proved that the linearity,the precision and the reclaimation rate are good enough . The method is convenient and the result is reliable.更多还原
