The Selective Removal of Nitrate and Nitrite from Polluted Water.

摘要

The basic idea was to add known nitrate selective compounds to currently available ion exchange resins to produce a resin that would selectively remove nitrate from contaminated waters,be easy to handle,and be capable of regeneration. Three such resins were made and tested and were found to have some selectivity but were entirely inadequate with regards to capacity. The compounds used were alpha-phenyl-alpha-hydroxy-beta-diethylaminoethane and alpha-phenyl-beta-diethylaminoe-thyl-p-nitrobenzoate on Bio-Rex-70and Bio-Gel P-300 , P-30and P-4. Studies were also begun using nitron and N-diet.
