novel dispersive liquid-liquid microextraction (dllme), coupled with high performance liquid chromatography with photodiode array detection (hplc-dad) has been applied for the extraction and determination of cyproheptadine (cph), an antihistamine, in human urine samples. in this method, 0.6 ml of acetonitrile (disperser solvent) containing 30 µl of carbon tetrachloride (extraction solvent) was ...
in this study, a rapid, simple and sensitive ion mobility spectrometry (ims) method with corona discharge as ionization source was described for the morphine determination in human urine. morphine was extracted and purified from urine samples using solid phase extraction procedure with c18 column. it can offer the clean extracts which no extra peaks were observed in ims. under operating experim...
The introduction of ecological sanitation (ECOSAN) toilets in villages near Bangalore hascreated opportunities for safer sanitation and recycling of human excreta, as fertilizers, in ruraland peri-urban areas. Field experiments were conducted at the University farm on French beansand Maize as the test crops in succession for 2 consecutive years in the same field. Differenttreatment combinations...
abstract venlafaxine, 1–[2–(dimethylamino)–1–(4–methoxyphenyl) ethyl]cyclohexanol hydrochloride is a novel non-tricyclic antidepressant. venlafaxine is a second generation antidepressant drug, has a neuropharmacologic profile distinct from that of existing antidepressants including tricyclic compounds, selective serotonin reuptake inhibitors and monoamine oxidase inhibitors. venlafaxine impart...
a user-friendly and inexpensive ionic liquid-based single-drop microextraction (il-sdme) method was developed to preconcentrate trace amounts of aminophenol isomers (aps) from human urine, hair dye and water samples prior to analysis by high performance liquid chromatography-ultraviolet spectrophotometry detection (hplc-uv). under optimum conditions (i.e., 3.5 µl of 1-hexyl-3-methylimidazolium ...
a new method was developed for the spectral resolution by further determination of three- and four-component mixtures of drugs in urine samples through the complementary application of multivariate curve resolution-alternating least squares with correlation constraint. in the current study, a simple method was proposed to construct a calibration set for the mixture of drugs in the presenc...
abstract the third millennium has started, but the world is facing with serious challenges in achieving international security and peace. various human rights violations have lead the states to find means to protect human rights. also article 55 of the united nations charter introduces the respect to human rights and fundamental freedom as the most suitable ways to realize peace and security. ...
metformin hydrochloride (mfh) is an oral anti-diabetic drug of biguanide class. two selective spectrophotometric methods were presented for the determination of mfh in pharmaceuticals. the methods were based on the measurement of yellow-coloured charge-transfer complexes formed between mfh and two poly-nitrophenols, namely, 2,4-dinitrophenol (dnp method, at 405 nm) and picric acid (pa method; a...
