The activity of catalysis of IER was affected by the chemical reactive process, it's inner and outer diffusion processes, serving time and esterified degree.

离子交换树脂的催化活性既受化学反应过程的控制，又受内扩散和外扩散的影响，其催化活性也受反应温度、使用时间的、酯化度等因素的影响。

At present, there are several ways in wastewater disposal, such as flocculating disposal, biochemistry, ion exchange and so on.

废水处理是一个重要的全球性问题，目前所使用的方法有絮凝沉淀法、生化法、离子交换法等。

The stability ofradioactive microspheres can be improved by coating with ploT-L-lactic acid; however,about 60% of the activity leaches from the microspheres in this process, and approximately10% of the activity leaches after washing with saline. Fortunately, 30% of the activityremained stably in the resin microspheres.

体外稳定性实验结果表明：1采用离子交换法制备的放射性树脂微球标记核素脱落严重，使用聚乳酸包被放射性树脂微球可以提高其稳定性，但是包被过程中约有60％核素脱落，生理盐水洗涤约有10％的核素继续脱落，不过剩余的30％稳定存在于树脂微球上。

Commutative ion resin of strong acid instead of hydrochloric acid neutralized sodium hydroxide meliorated step of subsequent treatment.
