Abstract: In this paper simple and convenient visual titrimetric method have been described for the determination of Cyproheptadine hydrochloride (CPH) i.e. an antihistamine drug in pure form and in its dosage forms with pyridinium fluoro chromate (PFC) reagent. The principle of this method involves the oxidation of Cyclohepten ring of the Cyproheptadine hydrochloride (CPH) by a known excess of potassium iodate in sulphuric acid medium followed by iodometric titration in presence of reagent pyridinium fluoro chromate (PFC). The reagent pyridinium fluoro chromate (PFC) used in this method is a versatile oxidizing agent of chromium (VI)...............

Abstract: Thestudy investigates the organochlorine pesticides residue level in air and soilat sites in Nairobi and Mount Kenya regions, Kenya. Air and soil samples from four sites were collected and analysed for selected organochlorine pesticides (OCP) using gas chromatography equipped with electron capture detector and confirmed using GC/MS. The targeted pesticides were α-HCH, β-HCH, γ-HCH (lindane), α- endosulfan, β-endosulfan and Endosulfansulfate. The samples were collected seasonally between the monthsof July 2012 and April 2013.........

Abstract: Millingtonia Hortensis (MH) plant leaves extract is reported as corrosion inhibitor of mild steel in 1N HCl. Weight loss measurements, Tafel polarization and electrochemical impedance spectroscopy techniques are employed to analyze the effect on mild steel corrosion. It was found from the results of weight loss method that the inhibition efficiency increased with increase in MH extract upto 10 ppm. Electrochemical impedance spectroscopic measurements indicated that charge transfer resistance increases with increasing inhibitor concentration. Potentiodynamic polarization studies revealed that MH extracts act as mixed-type inhibitor. Scanning electron microscope (SEM) was used to analyze the surface adsorbed film.
