Ultraviolet Absorption of Sodium Chromate and Its Application in the Study of the Effects of UV-B on Plants
铬酸钾溶液紫外吸收特征及在研究UV-B生物学效应中的应用

To determine a better way to use sodium chromate solution to remove UV-A and UV-C from UV-B light source,ultraviolet absorption characteristics of sodium chromate at different concentrations and pH levels were studied.The physiological activities and biochemical component of Nostoc commune under UV-B light source with and without filtration by sodium chromate were also studied.Results showed that sodium chromate works well to remove UV-C and UV-A at a concentration of 0.4 mmol/L and pH 8.Compared with filte...
