Recently, cloud point extraction (CPE) has been an attractive subject as an alternative to liquid–liquid extraction. The technique is based on the property of most non-ionic surfactants in aqueous ...solutions to form micelles and become turbid when heated to the cloud point temperature. This review covers a selection of the literature published on applications of CPE in determination of metal ions over the period between 2004 and 2008.

Paracetamol is a common analgesic and antipyretic drug that is used for the relief of fever, headaches and other minor aches and pains. Their determination in pharmaceuticals is of paramount ...importance, since an overdose of paracetamol can cause fulminating hepatic necrosis and other toxic effects. Many analytical methodologies have been proposed for the determination of paracetamol. The aim of the present study is to evaluate the utility of different techniques for quantification of paracetamol content in pharmaceutical formulations and biological samples.
Vortex-assisted liquid–liquid microextraction employed for the isolation and preconcentration of analytes can be used together with various detection techniques in order to obtain a very versatile ...tool for the chemical analysis. This allows the analyzing of a great variety of analytes in very diverse concentrations. This review is an update of the manuscript published in 2014 by the same authors.
cis-Diamminedichloroplatinum(II) (cisplatin) is a important chemotherapeutic drug for cancer treatment since 1978. Unfortunately, because of the severe side-effects like nephrotoxicity, ototoxicity, ...etc., they are administered in small doses at low concentration establishing the maximum limit dosage to 100
mg/m
2 (21 days).
A variety of analytical methods have been proposed for the determination of cisplatin in biological fluids and tissues that permit the accurate determination at or below the part per billion level in the native sample. The purpose of the current review is to provide a systematic survey of the latest analytical techniques for the determination of cisplatin in biological samples.
Several techniques have been proposed for treatment of spectrophotometric data, with the objective of extracting a largest amount of analytical information from spectra composed of unresolved bands. ...Undoubtedly, a major success was achieved by derivative treatment of the absorbance curves-plotting of the first or a higher order mathematical derivative of absorbance against wavelength (d
A/d
λ). Derivative spectrophotometry has been applied to many chemical systems, such as pharmaceuticals, foods, cosmetics, and environmental samples.
The instrumental development and analytical applications of derivative UV–vis regions absorption spectrophotometry produced in the last 5 years (since 2004) are reviewed.
Omeprazole, a gastric acid pump inhibitor, dose-dependently controls gastric acid secretion; the drug has greater antisecretory activity than histamine H
2-receptor antagonists.
Omeprazole has been ...determined in formulations and biological fluids by a variety of methods such as spectrophotometry, high-performance liquid chromatography with ultraviolet detection and liquid chromatography coupled with tandem mass spectrometry. The overview includes the most relevant analytical methodologies used in its determination since the origin still today.

Rh is contained in catalyst in much smaller quantities than Pt. For this reason, the database for this metal with respect to emissions from catalytic converters is much smaller than that for ...platinum, thus precluding a quantitative risk assessment. Accurate determinations of the rhodium have always been difficult tasks. The metal is often present at trace levels in sample types of complex composition. This situation has improved recently due to developments of instrumental methods and their applications to analyses of rhodium in a variety of matrices. The purpose of this review is to describe the analytical sensitive methods by inductively coupled plasma spectrometry.
Furosemide (FUR), a drug that promotes urine excretion, is used in the pharmacotherapy of various diseases and is considered as a doping agent in sports. FUR is a powerful diuretic (water pill). This ...medicine is used to treat excessive fluid accumulation and swelling (edema) of the body caused by heart failure, cirrhosis, chronic kidney failure, and nephrotic syndrome.
Owing to its extensive use as a powerful diuretic, FUR has long attracted the attention of many analysts. A variety of analytical methods have been proposed for the determination of FUR in biological fluids and pharmaceutical samples. The revision includes the most relevant analytical methodologies used in its determination from the nineties decade at present.
