摘要
为了推动有关分光光度法测量水体色度的国家标准的建立,对美国和台湾地区的水体色度标准检测方法进行了研究,提出了新的基于三波长透射率测量水体色度的方法。根据现行国家标准中的色度学相关数据,选择在595、555和445 nm 3个波长处的光谱透射率计算水样的三刺激值,依照国标推荐的色差公式建立了测量水样色度的标准检量线。利用所提出的新的水体色度测量方法对5个水样的色度值进行了实际测量,结果表明,新的测量方法所得到的水体色度值与铂钴比色法一致。
A new method of water color determination using three-wavelength luminous transmittance was proposed in order to promote the establishment of national standard for water color determination by spectrophotometry, which was based on studies from the standard methods of the United States and Taiwan region. Accord- ing to the related colorimetrie data in current national standards, three wavelengths in 595, 555 and 445 nm were selected to calculate the tristimulus values. Then, the standard calibration curves for determination of water color were established on basis of the color difference formulas recommended by the Chinese national standards. In the end, some water samples were measured by the new method, and the results showed that the three-wavelength method for measuring water color was consistent with the platinum-cobalt colorimetry.
