In the present investigation, simple, rapid, selective and sensitive extractive spectrophotometric method has been developed for the and short analytical time.KEYWORDS: Alloy samples, bismuth(III), CBIMMT, Extractive spectrophotometric determination, pharmaceutical samples. INTRODUCTIONBismuth is a one of the most common element in the environment due to its consumption for a variety of purposes. It has two main oxidation states as bismuth(III) and bismuth(V).[1] Out of these, pentavalent state of bismuth is thermodynamically unstable while trivalent state of bismuth is stable. [2] In the earth crust, the existence of bismuth is about 8.0µg kg -1 and 0.2 µg L -1 in the sea. Bismuth has many applications in variety of fields including pharmaceuticals such as antacids, antiseptic, antibacterial, anti-ulcer, anti-HIV and radio therapeutic agents and ulcer. [3] It is widely used in cosmetics such as hair dyes and topical dermatological creams [4][5] as a reagent for purification of sugar [6] , as an additive in metallurgical operations, in alloys of some semiconductors and in the preparation and recycling of uranium nuclear fuels. [7] In recent days, Bi 2 Te 3 is widely used as a cooling substance and for low temperature thermoelectrical power generation. Bismuth containing pharmaceuticals have long been used for the healing some microbial infections, gastro-intestinal track disorder as indigestion, nausea and heartburn. Bismuth in the form of its sub carbonates and sub galletes are also useful for the cure of diarrhea, dysentery. [8][9] In addition to these useful applications, a number of toxic effects are also observed due to bismuth and its compounds like neurotoxic, nephrotoxic, osteoarthrapathy, kindey damhage symptoms, nephropth and hepatitis. Thus nowadays, enormous attention has been focused towards the quantitative determination of bismuth species in some matrices such as sea water samples, pharmaceuticals, ores, soils.Literature survey revealed that there are several analytical reagents has been synthesized for spectrophotometric determination of bismuth(III) on the basis of complexation reaction. World Journal of Pharmacy and Pharmaceutical SciencesHowever, these reagents have been criticized demerits like few showed maximum absorbance in UV region, some requires heating for complexation, some requires use of surfactants, more equilibration time, prolonged standing time to develop a maximum absorptivity of the species, low sensitivity and also lack of selectivity (Table 1). [10][11][12][13][14][15][16][17] Regarding to solvent extraction technique, new methods are developed for the determination of traces of bismuth(III) like solid phase extraction (SPE) [18] , dispersive liquid-liquid micro extraction (DLLME) [19] , cloud point extraction (CPE) [20] , solidified floating organic drop microextraction (SFODME).[21] However these methods also suffer from several demerits.SPE and DLLME microextraction methods are more complex, time consuming and requires multi-step for preconcentration of analytes...
