Antifouling paint booster biocides (Irgarol 1051 and diuron) in marinas and ports of Bushehr, Persian Gulf
TL;DR: Pollutions in ports and marinas of Bushehr located in the Persian Gulf showed that Irgarol and diuron pollutions were less than the average of reports from other parts of the world.

Antipsychotic drugs in hospital wastewater and a preliminary risk assessment.
TL;DR: The environmental risk quotient for clozapine, chlorpromazine and risperidone was ˃600, a very high-risk index, which signals the need for a better control of the emission of antipsychotics and an improvement of the wastewater treatment, especially, with regard to wastewater discharged from the hospital psychiatric wing.

A fully automated effervescence assisted dispersive liquid-liquid microextraction based on a stepwise injection system. Determination of antipyrine in saliva samples.
TL;DR: A first attempt to automate the effervescence assisted dispersive liquid-liquid microextraction (EA-DLLME) has been reported and the performance of the suggested approach is demonstrated by determination of antipyrine in saliva samples.
Journal ArticleDOI
A rapid and simple pretreatment method for benzoylurea insecticides in honey samples using in-syringe dispersive liquid-liquid microextraction based on the direct solidification of ionic liquids.
TL;DR: A pretreatment method using in-syringe dispersive liquid-liquid microextraction based on the direct solidification of ionic liquids before high performance liquid chromatography analysis was developed for the determination of benzoylurea insecticides (BUs) in honey samples with satisfactory results.
Journal ArticleDOI
Simultaneous derivatization and extraction of chlorophenols in water samples with up-and-down shaker-assisted dispersive liquid–liquid microextraction coupled with gas chromatography/mass spectrometric detection
TL;DR: UDSA-DLLME performed with higher extraction efficiency and precision compared with the other methods, and the common requirement of disperser solvent in DLLME could be avoided.

Solvent microextraction into a single drop.
TL;DR: An analytical technique is described which combines solvent extraction with gas chromatographic (GC) analysis in a simple and inexpensive apparatus involving very little solvent consumption and is in good agreement with a convective-diffusive kinetic model.

Liquid-Phase Microextraction in a Single Drop of Organic Solvent by Using a Conventional Microsyringe
Y. He and,Hian Kee Lee +1 more
TL;DR: In this article, two modes of liquid-phase microextraction (LPME) were developed for capillary gas chromatography, i.e., static and dynamic LPME, which involve the use of very small amounts of organic solvent in a conventional microsyringe.

Mass Transfer Characteristics of Solvent Extraction into a Single Drop at the Tip of a Syringe Needle
TL;DR: In this article, the authors measured the amount of a sample compound extracted into a 1-μL drop of n-octane suspended in a stirred aqueous solution from the tip of a microsyringe needle.
