Abstract

The objective of this study was to extend the properties of Ceramic Pot Filters (CPF) with arsenic removal capabilities by incorporating Nano Zero Valent Iron (nZVI) and Composite Iron Matrix (CIM) in the clay mixture before firing. In batch experiments it was found that with 50g/L crushed material of a fired blank filter and of fired filters amended with ZVI the same small amount of arsenic was removed, while ZVI itself is a good arsenic adsorbent. Crushed material of unfired filters containing ZVI showed much faster arsenic removal compared to fired filters. The loose of effectiveness of the fired-in ZVI is probably attributed to the intensive oxidation of the ZVI that took place during firing and to the less available surface sites due to incorporation in the clay. It is therefore not recommended to incorporate ZVI in CPF before firing.
