lipidfree extraction of pcbs from fat-containing matrixes using accelerated solvent extraction: florisil, basic alumina, neutral alumina, acidic alumina, and sulfuric acidimpregnated silica. all of the fat retainers generated fatfree extracts when the fat/fat retainer ratio was : . sulfuric acid-impregnated

silica and florisil were the only retainers that gave completely clear extracts, and the former was the only not to show any reaction when treated with sulfuric acid after the extraction. using sulfuric acidimpregnated silica as fat retainer, on-line cleanup of fatcontaining matrixes was possible, as...
