A new, sensitive, simple, inexpensive and fast kinetic spectrophotometric method was developed for the determination of trace amounts of morphine over the range of 12-60ng/mL. The method is based on the catalytic effect of morphine on the reaction of bromate and methylene bluein acidic media is reported. The reaction was monitored spectrophotometrically by 60 ng/ml measuring the decrease in absorbance of methylene blue at 665 nm with a fixed-time 0.5-2.5 min from initiation of the reaction. The detection limit is 0.8 ng/mL and relative standard deviation of 12and 52ng/mLmorphine for 6 replicate measurements was 1.50 and 0.87%respectively. The method 12 and 52 ng/ml was applied to the determination of morphine inpharmaceutical samples % respectively.

“…5 The decrease in the level of ACh from the standard levels in the cortex and hippocampus, 6 could help the assembly of amyloid b peptides into amyloid brils, which results in Alzheimer's disease (AD). [7][8][9][10][11] In fact, AChE plays an essential role in the development of AD. AChE inhibitors are usually used for the inhibition of ACh hydrolysis and increase the ACh concentration.…”

“…Several methods for determination of this drug have been reported in the literature, including high performance liquid chromatography [5][6][7][8][9][10][11][12][13][14][15][16], capillary zone electrophoresis [17], spectrofluorimetry [18,19], X-ray fluorescence spectrometry based on the formation of ion-pair associates with zinc thiocyanate [20] and voltammetric methods [19,20]. Electrochemical methods have received considerable interest due to their higher selectivity, lower detection limit, lower cost and faster operation than other reported methods [21,22]. Since the innovation of carbon paste electrodes (CPEs) by Adams, they have been widely used in many fields such as voltammetry, amperometry and potentiometry [23].…”

Electrochemical sensor was fabricated based on carbon paste electrode modified with an ionic liquid crystal ILC (2-chloro-1,3-dimethyl-imidazolidinium hexafluorophosphate) in presence of sodium dodecyl sulfate for the selective electrochemical determination of Terazosin (TZ) in presence of common interference compounds. The electrode performance was compared in presence of other ionic liquids ILs (1-Butyl-4-methyl pyridinium tetrafluoroborate) and (1-n-Hexyl-3-methyl imidazolium tetrafluoroborate). Ultrasensitive determination of Terazosin HCl at the ILC modified electrode in the linear dynamic ranges of 0.002 to 0.09 µmol·L −1 and 0.2 to 30 µmol·L −1 with correlation coefficients 0.996 and 0.995 and LODs 1.69 × 10 −11 mol·L −1 and 6.43 × 10 −9 mol·L −1 , respectively, were obtained. Selective determination of TZ in presence of uric acid and ascorbic acid and simultaneous determination of binary mixtures of TZ/dopamine, TZ/paracetamol and TZ/Morphine were also determined successfully using the modified sensor.
