磷酸锆是一种具有离子交换性能的无机载体,被广泛应用于离子交换体.研究不同晶型磷酸锆的载银工艺,探索银离子交换的机理并制备出高载银量的磷酸锆载银抗菌粉.以锆磷比为1:2的α-Zr(HPO_4)_2·H_2O和锆磷比为2:3的六面体磷酸锆为对象,研究在不同离子交换环境下对银离子的交换率.发现α-Zr(HPO_4)_2·H_2O在层间隙扩大的情况下,银离子交换量大于8.47%,而六面体磷酸锆在强酸高温环境中,银离子交换量大于4.45%.具有层状间隙的α-Zr(HPO_4)_2·H_2O比六面体磷酸锆对银离子具有更高的交换容量.为研制具有高效长效抗菌要求的制品,如抗菌医用导管做好准备.

Zirconium phosphate is a inorganic carrier which can be used for ion exchange.Study ion exchange parameters of two type zirconium phosphate with different structure to find the way how ion exchange happened.And got nano silver antibacteria agents with high silver.We studied α-Zr(HPO_4)_2·H_2O which Zr/P=1:2 and hexahedral zirconium phosphate which Zr/P=2:3 and found different ion exchange way with these two zirconium phosphate.High temperature in acid surroundings can raise the ion exchange amount and ratio when Ag~+ was exchanged into hexahedral zirconium phosphate,and the Ag~+ content can be more than 4.45%.When α-Zr(HPO_4)_2·H_2O was studied,widen space between layers can raise the amount and exchanged ratio of Ag+ shapely.We considered the different ion exchange way of these two carriers and deduce that α-Zr(HPO_4)_2·H_2O can carry more Ag+ than hexahedral zirconium phosphate.This study will helpful when making products with good antibacterial capability,such as catheter used in medical treatment.
