The determination of iodine in cheese by neutron activation combined with separation of iodine by selective retention on Dowex 2-X8
Description
Iodine has been determined in Norwegian cheese by combination of neutron activation and subsequent separation of radioiodine (128I) by selective retention on Dowex 2-X8 anion exchange resin. Iodine may be detected down to 5ng in terms of absolute amounts. In terms of concentration the detection limit was 10ppb. Results showed a precision of 5 percent at a concentration level of 1ppm.
