摘要
通过测定全程吸附-脱附等温线,研究了钛、锆、铬、铁、镍等几种过渡金属聚合羟基阳离子交联蒙脱土的孔径分布和孔体积。实验结果表明,几种试样经120C 和400C 热处理后,孔径最为集中的部分约在18~26和15~30(?)范围内;孔体积最为集中的部分,除个别的外,约在0.26~0.31和0.26~0.49ml·g^(-1)范围内。
Pore-size distributions and pore-volumes of some polyhydroxy transition-metal-cations,includ-
ing titanium,zirconium,chromium,iron and nickel pillared montmorillonites have been studied by
their adsorption-desorption isotherms.The experimental results show that the most concentrated area
of pore-size distributions are essentially in the range of 18~26 and 15~30(?);pore-volumes are es-
sentially in the range of 0.26~0. 31 and 0.26~0. 49ml·g^(-1) after heat treatment at 120 and
400C respectively.
