光度分析中经常使用各种标准溶液作条件试验、校正曲线、常数测定、机理探讨等等。因此,正确配制、使用和贮存标准溶液是测定准确可靠的前提。但是,在标准溶液的贮存和使用过程中,常常发生非人为的沾污现象,如配制方式、贮存容器和环境、实验室条件等等均可能影响标准溶液浓度的变化。现将本实验室十年来记录的结果加以整理,供同行参考。实验部分 1.标准溶液的配制:铍、镁、钙、锶、钡、银、铅、锆、铂、铑、汞标准溶液用纯盐 Photometry often use a variety of standard solutions for conditional testing, calibration curves, determination of constants, mechanisms and so on. Therefore, the correct preparation, use and storage of standard solution is to determine the accuracy and reliability of the premise. However, inadvertent contamination of the standard solution during storage and use of the standard solution, such as formulation, storage container and environment, laboratory conditions, etc., may affect the standard solution concentration. Now the laboratory records the results of a decade to be sorted for peer reference. Experimental Part 1. Standard solution preparation: Beryllium, magnesium, calcium, strontium, barium, silver, lead, zirconium, platinum, rhodium, mercury standard solution with pure salt
