摘要

本文研究了聚乙烯毛细管共辐照接枝苯乙烯和经浓H

磺化后制成阳离子交换管。阐明了聚乙烯毛细管辐射接枝苯乙烯时，剂量、剂量率、单体浓度、溶剂、温度和交联剂等对接枝率的影响。探讨了辐射接枝条件与离子交换管性能之间的关系。在本文所述的最佳条件下，可制得内径0.8mm、长20m、交换容量0.7Meq/g、10s相对交换率达60%以上（流速20ml/min）的聚乙烯阳离子交换毛细管。这种离子交换管循环使用200次后交换容量无显著下降。

Abstract

The synthetic process of polyethylene cation exchange capillary via radiation grafting polystyrene by simultaneous irradiation with

Co γ-ray source and sulfonation with concentration H

was studied. The effects of dose

dose rate

monomer concentration

solvents

temperature and crosslinking agents on the graft copolymerization of styrene with polyethylene capillary were illustrated. The relationship between the radiation grafting conditions and the properties of ion-exchange capillary were examined. A polyethylene cation exchange capillary with I. D. 0.8mm

length 20m

exchange capacity 0.7 Meq/g

60% capacity in 10 s (flow rate 20ml/min) was prepared. No significant loss of capacity was found from this ion-exchange capillary after 200 adsorption/regeneration cycles.
