ABSTRACT:
For the removal of trace quantities of iodine-containing contaminants from corrosive liquid feed streams, an adsorbent with distinct advantages over prior-art materials is provided. The treatment method involves the use of a metal phthalocyanine compound where the metal selected from the group consisting of silver, mercury, copper, lead, thallium, palladium, or mixtures thereof. Such metals are known to be reactive with the iodine-containing contaminants in the feed stream. Furthermore, the metal phthalocyanine is deposited on a carrier material selected from the group consisting of an activated carbon, a phenolic polymer, and an inorganic refractory metal oxide. Such adsorbent materials have proven substantially insoluble even in corrosive liquid feed streams associated with the invention. Reactivation and regeneration techniques, which are generally incompatible with prior-art adsorbent materials, are also disclosed.
