Data for: The in situ technique of aqueous binding concentration and diffusion for measurements of arsenate concentrations in lake waters

measurements of light absorbance in a binding solution by a paired LED. the binding solution is used in a diffusive gradients technique for pre concentration of arsenate in water.采用配对发光二极管（LED）对结合液的光吸光度进行测量。该结合液应用于扩散梯度技术，用于水体中砷酸盐的预富集。
