Trace determination of bisphenol-A in landfill leachate samples by dispersive liquid- liquid microextraction followed by high performance liquid chromatography

Abstract

ABSTRACT. A simple, rapid and efficient sample pretreatment technique, termed dispersive liquid-liquid microextraction (DLLME), was developed as an extraction methodology to determine bisphenol-A (BPA), in landfill leachate samples prior to high performance liquid chromatography (HPLC)-ultraviolet detection. Some effective parameters, such as pH, extraction and disperser solvent type and their volumes, time of extraction and salt effect have been optimized using the one-factor-at-a-time approach. Under the optimum conditions, the preconcentration factor 25 was obtained from only 5 mL of the sample. The calibration graph was linear in the range of 5-500 µg L -1 with the detection limit of 1.5 µg L -1 . The relative standard deviation (RSD) for ten replicate measurements of 20 µg L -1 of BPA was 2.5%. Finally, the method was successfully applied for the extraction and determination of BPA in some landfill leachate samples with a relative recovery of 98-109% and RSD less than 5%.

Bisphenol A analysis and quantification inconsistencies via HPLC-UV: a systematic review with technical notes

“…3 A Main purpose of the analyzed studies as revealed by the publications in Table S1. B Overlapped main purposes with other secondary objectives of the analyzed papers [64] or by air pollution near polycarbonate molding plants [65], bee pollen [66], mussels [67] and brine shrimp [68]. Food contamination was determined in meat samples [53], beverages [55,69,70], milk [59,63,71,72], oils [56,63], and canned food products [59,71,73] with most studies revealing that BPA could be leached from the plastic can linings, packaging, and bottles [53,55,56,71,[74][75][76].…”

Determination of malathion by homogeneous liquid-liquid micro extraction via flotation assistance combined with gas chromatography in water samples

“…The solvent microextraction technique such as dispersive liquid-liquid microextraction (DLLME) [18][19][20][21][22][23] which overcomes these problems by reducing the amount of the organic solvent have been used to extract and determination of OPPs pesticides [24]. Extraction solvents often used in DLLME are chlorobenzene, carbon tetrachloride and chloroform with higher density than water and all of which are potentially toxic to human and the environment.…”

Pre‐concentration of trace amount of bisphenol A in water samples by palm leaf ash and determination with high‐performance liquid chromatography

“…Recently, endocrine disturbing chemicals have been identified as the most notorious contaminants (Canale et al, 2010;Jing et al, 2011;Cai et al, 2004). Out of this, about 100 tons is released into the environment (Bahramifar et al, 2014;Rykowska and Wasiak, 2006). BPA is produced worldwide, with an estimated production of 3.9 million tons in 2006 (Ballesteros-Gómez et al, 2009).…”

“…BPA is produced worldwide, with an estimated production of 3.9 million tons in 2006 (Ballesteros-Gómez et al, 2009). Out of this, about 100 tons is released into the environment (Bahramifar et al, 2014;Rykowska and Wasiak, 2006). BPA is a typical product of the industrial society produced in large quantities worldwide, 90% or more being used as a monomer for the production of polycarbonate plastics (PC), epoxy resins used to line metal cans and in many plastic consumer products including toys, water pipes, drinking containers, eyeglass lenses, sports safety equipment, dental monomers, medical equipment and tubing, polysulfone, polyacrylate, polyetherimide, unsaturated polyester and phenolic (Asimakopoulos et al, 2012;Vandenberg et al, 2007).…”
