In the last decade, a global trend of escalating ecstasy (MDMA, MDA, MDEA, MBDB) use was observed. Mentions on medical death certificates, last year's ecstasy use, number of drug offenders, seizures, prices and dosage levels figures were used for this descriptive and correlational study. Figures (1994-2003) were taken from the UK General Mortality Registers, from the Home Office Statistical Bul...

To facilitate the analysis of targeted drugs under high sample volume testing environment, an extraction, derivatization and gas chromatographic-mass spectrometric analysis method was developed for simultaneously determination of amphetamine (AMP), methamphetamine (MAMP), 3,4-methylenedioxyamphetamine (MDA), 3,4-methylenedioxymethamphetamine (MDMA), 3,4-methylenedioxyethylamphetamine (MDEA), ke...

We describe a simple HPLC method which is suitable for the routine confirmation of immunoassay positive amphetamine urine samples. The precolumn derivisation method employing sodium naphthaquinone-4-sulphonate was found to have adequate sensitivity, selectivity and precision for the measurement of amphetamine, methamphetamine, 3,4-methylenedioxymethamphetamine (MDMA), 3,4-methylenedioxyamphetam...

Carbon dioxide emissions are the largest greenhouse gases contributor, which is attributed to global warming. Therefore, capture of CO2 necessary, especially from large point sources. Post-combustion using chemical solvents most matured technology. In this paper, mixed methyldiethanolamine (MDEA) and piperazine (PZ) were studied potentially address some issues related use conventional monoethan...

the object of this work is solubility correlation and prediction of co2 and h2s in various aqueous alkanolamines using the electrolyte cubic square-well equation of state (ecsw eos) [haghtalab, a.,mazloumi, s. h., (2009a), fluid phase equilib.,285,96-104]. the eeos systematically is applied to describe the solubility of acid gases in various alkanolamine solutions, including mdea, mea, dea, amp...
