ABSTRACT
In Chapter 9, we saw that contaminants can be broken up into six broad cat egories: organics, oxides, particles, metals, mobile ions, and crystal damage. Whereas Chapter 9 dealt with organics, this chapter focuses on the deposition and removal of metallic and mobile ions. Most metals present in the solution are ionized, and therefore this chapter is applicable to any ionic contamination, be it metallic ions, mobile ions, or even anions. However, because of the tech nological importance of metallic ions and metallic impurities, we will mainly refer to ionic contamination as metallic contamination.
