The luminosity having studied sulfhydryl group cotton separates the beneficiation Bi-5-Br-PADAP coloration system beam split models after the main body of a book determining water trace bismuth method. In pH = 3.5 acetic acid- acetic acid sodium solution medium, Bi (III) forms 1:2's stable complex compounds and under having the condition that the emulsifier there exists in OP, with 5-Br-PADAP , it's maximal sorption wavelength lambdamax is get along in 590 nm , apparent suck mole the modulus is 6.226 X 104 L/ (mols & # only 8226; Cm-1); 0 ~ 15 & micro; The g/25mL range inner bismuth is observed Langbobier law. Use sulfhydryl group cotton to carry out separation to the ion affecting the disturbance determining, method admeasurement result is all that could be desired , operation goes to the lavatory simplely. Acidity, washes the best medium separating beneficiation in the experiment to sulfhydryl group cotton taking off liquid acidity and redressing to take off liquid dosages having carried out investigation and discussion. This follows few characteristics having coloration speed quickly , disturbing an element , apply to water trace bismuth

In this paper, the separation and preconcentration Sulfhydryl Cotton Bi-5-Br-PADAP color Determination of trace bismuth in water method. At pH = 3.5 acetate - sodium acetate solution medium, and emulsifier OP under the conditions of existence, Bi (Ⅲ) with 5-Br-PADAP form a stable 1:2 complex with maximum absorption wavelength λmax at 590 nm, the apparent molar absorptivity of 6.226 × 104 L / (mol • cm-1); 0 ~ 15 μg/25mL bismuth within the scope of compliance with the law of朗伯比尔. Determination of the effects of interference with sulfhydryl cotton-ion separation method the results are satisfactory, the operation is simple and convenient. Experiments on the separation and preconcentration sulfhydryl cotton the best medium acidity, the amount of eluate eluate acidity and discussed. This method is faster than color, less interference with the characteristics of elements, the water used in the determination of trace bismuth, can be satisfied with the results.

This article studied qiu the base cotton and kapok separation to concentrate in the Bi-5-Br-PADAP colored system spectrophotometric method determination water the micro bismith method. In the pH=3.5 ethanoic acid - sodium acetate solution medium, and has under the emulsifier OP existence condition, Bi (Ⅲ) forms the stable 1:2 complex compound with 5-Br-PADAP, its biggest absorption wave length λmax in 590 nm place, apparent molar absorption absorptivity for 6.226×104 L/(molcm-1); in 0~15 g/25mL scopes the bismith observes Lambert the Bill law. Carries on the separation regarding the influence determination's interfering ion with qiu the base cotton and kapok, the method determination result is satisfying, the simplicity of operator is convenient. In the experiment the best medium acidity which, the eluent acidity and the eluent amount used concentrated to qiu the base cotton and kapok separation has carried on the discussion. This law has the colored speed to be quick, the disturbance element few characteristics, apply in the water the micro bismith determination, can obtain satisfaction the result.

This study used cotton separation and enrichment Bi - 5 - Br - PADAP colour-display system spectrophotometry trace bismuth method. In pH = acid acetic acid sodium solution - 3.5 and emulsifier medium, under the condition of existence OP Ⅲ (Bi) and 5 - PADAP to form stable Br - 2, the maximum absorption wavelength lambda Max 590 nm, apparent molar absorption coefficient for 6.226 x 104 L / (mol cm - 1);, 0 ~ 15 g / 25mL range maximum tire-road friction coefficient by lang "bill laws bi. To affect the interference with sulphur ion, cotton method satisfactory results, easy to operate. In the experiment of cotton separation and enrichment of mercaptoacetic best medium acidity, the eluent acidity and the eluent dosage is discussed. Method is faster, interference color, fewer elements in water trace bismuth, can obtain satisfactory results.
