中文摘要：
设计了利用手机成像数码比色法测定水样中6价铬的实验，水样中6价铬经二苯碳酰二肼显色后用手机拍摄溶液图像，用Photoshop软件读取图像中显色液绿色通道的亮度值，该亮度值与溶液中铬的质量浓度呈线性关系，从而计算样品中6价铬的含量，对拍摄方式和图像读取方式进行了讨论。样品测定结果与分光光度法一致，加标回收率在98．0％～102．0％之间。该方法不使用专业仪器设备，简便、快速、准确，可实现现场检测。由于只使用学生自带的智能手机为检测设备，可极大地激发学生的实验兴趣和创新、探索精神。
英文摘要：
A new smartphone imaging digital colorimetric method for determination ot Cr（Ⅵ） in water was proposed. The Cr（Ⅵ） from aqueous solution reacts with diphenylcarbazide to form a color complex, then the digital images from the solution above was captured by a smartphone and imported into the Photoshop software to read the brightness value of green channels. The experimental data showed that brightness value is linearly correlated with the concentration of Cr（Ⅵ） in solution. The influential factors such as shooting mode and image reading mode were studied and optimized. The results were consistent with the spectrophotometric method with the recovery of 98.0%-102.0%. This obtained method is rapid, accurate, easy to operate and can be used in on-site analysis without professional instruments. The presented method of students＇ own smartphones as only testing equipment can greatly stimulate students＇ interests in experiment and innovative spirit.
