本文以钠型蒙脱土（Ｎａ－Ｍｔ）为原料，以羟基铬聚合阳离子为交联剂制备出羟基铬交联蒙脱土（Ｃｒ－Ｍｔ）并对其物化性能进行研究。结果表明Ｃｒ－Ｍｔ的物化性能优于Ｎａ－Ｍｔ，ｄ＿（００１）值１．６～１．９ｎｍ，比表面积８０～１９０ｍ￣２·ｇ￣（－１），１．８～５．０ｎｍ的孔约占半数以上，表面总酸量为６．１×１０￣（－４）～６．５×１０￣（－４）ｍｏｌ·ｇ￣（－１）、阳离子交换量在９．０×１０￣（－３）～４２×１０￣（－３）ｍｏｌ／１００ｇ样，但其热稳定性有待进一步提问。
In this paper, sodium montmorillonite (Na-Mt) as raw material, hydroxyl chrome polymerization cations crosslinker prepared hydroxy chromium-crosslinked montmorillonite (Cr-Mt) and its physical and chemical properties. The results show that the physical and chemical properties of Cr-Mt are better than that of Na-Mt, the d_ (001) value is 1.6 ~ 1.9nm, the specific surface area is 80 ~ 190m ~ 2 · g ~ (-1) The pore volume accounts for more than half of the total pore volume, and the total surface acid amount is 6.1 × 10 -4 to 6.5 × 10 -4 mol · g -1. The cation exchange capacity is 9.0 × 10 -6 ~ (-3) ~ 42 × 10 ~ (-3) mol / 100g samples, but its thermal stability needs further questions.
