Stir-bar sorptive extraction (SBSE) is a sample-preparation technique that involves extraction and enrichment of organic compounds from a liquid sample. The technique is based on the principle of sorptive extraction. A large amount of an extraction phase (e.g., polydimethyl siloxane) is coated on a stir bar to extract an analyte. The number of studies that have used SBSE has linearly increased in...
The effects of saponification conditions (temperature and water content of saponifying solution) on the determination of chlorinated biphenyls (CBs) in marine sediments were investigated. Although highly chlorinated biphenyls (nona- to deca-CBs) decomposed during high-temperature saponification, the degree of degradation was reduced by adding water to the ethanolic potassium hydroxide saponifying...
