摘要： This invention relates to ion exchange resins that have a reduced amount of physically adsorbed organic compounds, as well as methods of producing and using such resins. In particular, the amount of extractable total organic carbon on the resins may be less than about 200 parts per trillion by wet weight, as measured using gas chromatography/mass spectrometry. This invention also relates to methods of treating water that use such resins.

摘要： The invention includes an operating method for the continuous purification of a liquid utilizing either single or dual ion exchange vessels, each vessel being physically divided into one or more discrete of ion exchange zones, each zone having an inlet and an outlet. A valving means at the inlet and outlet of each ion exchange zone provides communication between adjacent ion exchange zones as well as to feed, product, water and regenerant chemical streams. In one aspect of this invention a first vessel contains a discrete plurality of cation exchange zones and a second vessel contains a discrete plurality of anion exchange zones. In another aspect of this invention, a single vessel contains a plurality of discrete cation exchange zones and a plurality of discrete anion exchange zones. In another aspect of the invention, each ion exchange zone is contained within a single vessel.
摘要翻译：本发明包括使用单离子交换容器或双离子交换容器连续净化液体的操作方法，每个容器在物理上分成一个或多个离散的离子交换区域，每个区域具有入口和出口。在每个离子交换区的入口和出口处的阀装置提供相邻离子交换区之间的连通以及进料，产物，水和再生化学气流。在本发明的一个方面，第一容器包含分立的多个阳离子交换区，第二容器含有离散的多个阴离子交换区。在本发明的另一方面，单个容器包含多个离散的阳离子交换区和多个离散的阴离子交换区。在本发明的另一方面，每个离子交换区包含在单个容器内。
