General Properties of Exchange Media

An ideal ion exchange medium is one that fulfils the following criteria:

1. a regular and reproducible composition and structure;

2. high exchange capacity;

3. a rapid rate of exchange (i.e. an open porous structure);

4. chemical and thermal stability and resistance to 'poisoning' as well as radiation stability when used in the nuclear industry;

5. mechanical strength stability and attrition resistance;

6. consistency in particle size, and compatibility with the demands of the use of large columns in industry.

In addition some applications demand the ability to exchange a specific ion(s) selectively from high concentrations of other ions. This is particularly true for aqueous nuclear waste treatment and in hydrometal-lurgy. In some of these applications ion exchangers with lower capacities can be effective.

Solar Panel Basics

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
