摘要
针对现今国际上两种测量浊度标准（USEPA180．1和ISO7027），分析了两种标准所规定选用的浊度仪光源的优缺点，并进行了实验数据比较。得出了采用峰值波长在400-600nm的卤素钨灯为浊度仪光源时，测量结果受色度的影响较大；而采用峰值波长在860nm左右的红外光LED时基本不受水样中色度的影响。
According to the difference of two turbidimeter measuring standards （USEPA180. 1 and ISO7027）. This paper analyze the advantage and disadvantage of two different light source choosed by two standards and make comparison of the experimental data. The measuring value would be influenced apparently by color of the water when using tungsten lamp with a spectral peak response of the detection systems between 400-600 nm, while hardly influenced by color of the water when using infrared LED with spectral peak response at 860nm.
