Abstract:
Abstract A sonication technique is presented for the extraction of polychlorinated biphenyls (PCBs) from sediments. In addition, a quantitation scheme is described which allows peak-specific and, in many cases, congener-specific determination of PCBs. PCBs are quantitated by capillary column gas chromatography-electron capture detection, with internal standard calibration. Results utilizing sonication extraction were compared with those obtained by Soxhlet and steam distillation extractions of 3 U.S. Environmental Protection Agency (EPA) quality control sediment samples and 3 lake sediments kn

Each extraction method performed well in removing the 15 PAHs from both soils over a broad range of concentrations.

Abstract Microwave-assisted extraction (MAE), Soxhlet, soni cation, and supercritical fluid extraction (SFE) were compared in their ability to extract 95 compounds listed in U.S. Environmental Protection Agency Method 8250. Freshly spiked soil samples and 2 standard reference materials were extracted with hexane-acetone (1 + 1) by MAE and Soxhlet extraction, with methylene chloride-acetone (1 + 1) by sonication extraction, and with supercritical carbondioxide modified with 10% methanol by SFE. Results indicate that MAE is a promising extraction technique. Of 94 compounds for which we are repor

Abstract:
Galam bark has not been widely used, it was only stacked and burned. Tree bark usually contains lignocellulose and natural dye. This study aimed to evaluate the application of galam bark for natural dyes on fabric. Galam bark was extracted using soxhlet and maceration methods, with time and solvent extraction variations. The obtained natural dye was used for dyeing using lime and alum for fixation. The results showed that the soxhlet extraction with water as the solvent for 5 hours produced dye with pH value 7 (neutral) and color sharpness 21 PtCo. The soxhlet extraction with water as the solv

Abstract:
Petroleum hydrocarbons (PHC) are common soil contaminants. A number of methods have been used to extract PHCs from soil prior to quantification by gas chromatography (GC). These methods often require long extraction times and expensive, specialized equipment. A shaking method was assessed for simple, rapid removal of PHCs from contaminated soils. Shaking spiked and aged contaminated soils for 4 h with acetone:hexane (1:1) at a soil:solvent ratio of 1:30 (g:mL) recovered 74 to 108% of PHC, compared with a Soxhlet extraction, yielding a good correlation (4 h = −93.7 + 0.99 Soxhlet r = 0.99, P &l

In this research, the objective was to study the effect of extraction methods on finger prints and fatty acid profiles of beef fat and to obtain the chosen extraction method. This study consisted of two steps namely extracting beef fat using Soxhlet, Folch, Bligh and Dyer, and Hara and Radin methods as well as characterizing the finger print using FTIR and fatty acid profiling using GCMS.

This study investigated the coffee silverskin (CS) crude oil extraction process and characterization of physicochemical properties and enzymatic hydrolysis for fatty acids production. The soxhlet and ultrasonic extractions showed CS oil yield similar to 3.8% and 3.1%, respectively. CS oil extracted by soxhlet presented favorable physicochemical properties with the quality and was used as the feedstock for fatty acids production by enzymatic hydrolysis. The porcine pancreatic lipase showed hydrolytic activity of 1156 U.g-1 ± 13.4. Therefore, we verified the potential of application in biotransf

Abstract:
The aim of the study was to assess the fat content in selected animal-origin products (ie. black pudding, luncheon, wiener, bacon) as well as certified reference material (MUVA RM700 Boiled Sausage) using two analytical methods. One of them was the fat extraction using a Soxhlet technique, and the other one - the extraction using carbon dioxide in supercritical state. Methods based on Soxhlet extraction have been and are at present used as reference. This conventional method is cheap and accurate, and this is why it has been the most used extraction technique worldwide for a number of decades.
