생체시료로부터 미량 이부푸로펜의 고상추출에 사용될 흡착제들의 특성
김경례(Kyoung Rae Kim),심원희(Weon Hee Shim) 대한약학회 1992 약학회지 Vol.36 No.6
The sorption and desorption properties of four different solid adsorbents were evaluated for the trace enrichment of ibuprofen from biological samples. Chromosorb 107 gave the highest dynamic adsorption coefficient. Among the organic solvents examined, acetone gave the highest desorption coefficient. Using the Chromosorb 107 column, the optimum elution volume of the eluting solvent was evaluated from the breakthrough curve of ibuprofen. The usefulness of Chromosorb 107 as the solid adsorbent and acetone as the eluting solvent was examined for the solidphase extraction of ibuprofen from serum in the concentration range of 20~40mcg/ml.
생체실료로 부터 미량 디페닐히단토인의 고상추출에 사용될 흡착제의 특성

The sorption and desorption properties of four different solid adsorbents were evaluated for the trace enrichment of diphenylhydantoin from biological samples. Graphitized carbon black(GCB) gave the highest adsorption coefficient. And among the organic solvents examined, methanol gave the highest desorption coefficient. Using the GCB column, the optimum elution volume of the eluting solvent was evaluated from the breakthrough curve of diphenylhydantoin. The usefulness of GCB as the solid adsorbent was examined for the solid-phase extraction of diphenylhydantoin from serum in the concentration range of 20-50mcg/ml.
