Chemosphere | 1989

Application of supercritical fluid extraction of biological tissue samples for the determination of polychlorinated organics

K.S. Nam; Shubhender Kapila; D.S. Viswanath; Tom E. Clevenger; J. Johansson; A. F. Yanders

Abstract The use of supercritical carbon dioxide as an extraction medium in the determination of polychlorinated organics was investigated. The extraction procedure was found to be highly efficient and reproducible.


Chemosphere | 1991

Role of entrainers in supercritical fluid extraction of chlorinated aromatics from soils

M.H. Liu; Shubhender Kapila; A. F. Yanders; Tom E. Clevenger; A. A. Elseewi

Abstract The application of supercritical fluid technology holds considerable potential for removing toxicants from soil. The use of carbon dioxide at temperatures and pressures above its critical point was evaluated for removal of such contaminants as chlorinated pesticides, polychlorinated biphenyls and chlorinated phenols. Experiments were carried out to optimize the extraction parameters and define the role of entrainers under varied matrix conditions.


Chemosphere | 1990

Effect of Co-contaminants on the Disposition of Polychlorinated Dibenzo-p-dioxins and Polychlorinated Dibenzofurans in Saturated Soils

Ravi K. Puri; Shubhender Kapila; Y. H. Lo; Carl E. Orazio; Tom E. Clevenger; A. F. Yanders; A. A. Elseewi

Abstract The effect of such co-contaminants as chlorinated phenols, naphthalenes and petroleum oil on the partition behaviors of polychlorinated dibenzo-p-dioxins (PCDDs) was investigated. The results obtained indicate that the transport of PCDDs in a saturated environment can be directly attributed to colloidal suspensions of the co-contaminants.


Chemosphere | 1989

Application of a dual column reaction chromatography system for confirmatory analysis of polychlorinated biphenyl congeners

Dennis O. Duebelbeis; G. Pieczonka; Shubhender Kapila; Tom E. Clevenger; A. F. Yanders; J. D. Wilson

Abstract The present work describes the application of a dual column reaction chromatography system for congener specific analysis of polychlorinated biphenyls in human serum and adipose tissue samples.


Chemosphere | 1990

Application of a two-dimensional reaction chromatography system for confirmatory analysis of chlordane constituents in environmental samples

Dennis O. Duebelbeis; Shubhender Kapila; Tom E. Clevenger; A. F. Yanders

Abstract Confirmation of Chlordane components in fish tissue and sediment samples was performed with a two-dimensional reaction chromatographic system. A 30 cm length of nickel tubing was employed as an in-line hydrodehalogenation reactor.
