【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。更多还原

【Abstract】 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 bytheir adsorption-desorption isotherms.The experimental results show that the most concentrated areaof 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 and400C respectively.更多还原
