Storage characteristics of three selenium species in water

Publikováno v: Archives of Environmental Contamination and Toxicology. 25

The storage characteristics of selenate, selenite, and selenomethionine in low and high ionic strength water were investigated. Each water matrix, which contained all three selenium forms, was subjected to three different selenium concentrations (10,

Autor: R H Wiedmeyer, Lawrence M. Smith, R G Lehmann, J D Petty

Publikováno v: Journal of AOAC INTERNATIONAL. 66:673-676

Methods are described for determination of S,S,S-tributylphosphorotrithioate (DEF) at levels as low as 5 parts per billion in fish and 200 parts per trillion in water. Fish tissue extracts are subjected to gel permeation chromatography (GPC) and sili
