摘要

研究H3AsO4-H2O体系的物理化学性质是非常重要的，因为砷酸参与了用于生产AIIIBV半导体的arsine的电化学合成。用石笋法测定了不同浓度的砷酸溶液在20 ~ 80℃宽温度范围内的表面张力。在水溶液中砷酸是一种表面无活性物质，因为随着溶液中H3AsO4浓度的增加，其表面张力增大。

Surface Tension of Arsenic Acid Solutions

Investigation of the physicochemical properties of the H₃AsO₄–H₂O system is of great importance, since arsenic acid is involved in the electrochemical synthesis of arsine, which is used to produce A^IIIB^V semiconductors. The surface tension of arsenic acid solutions of various concentrations in a wide temperature range (20–80°C) was measured by the stalagmometric method. It has been determined that arsenic acid in an aqueous solution is a surface-inactive substance because, with increasing concentration of H₃AsO₄ in solution, its surface tension increases.
