From the sample of all types of milk powder 3 8 sections divided 4 parts of each brand to light intensity is measured by a method call with full specs on the metric rose 4 to take part and another Spike Standard Addition. 1.8 from the station, for example, two kinds of milk, whole foe Wright 6 3 share a portion of each brand to light intensity is measured by means of a call specification and full of rose and 3-part metric to make Spike Standard Addition.2. preparation of standard solution 2.1 prepare the Stock solution of the acid. 3-CD-2-hydro investigated naphtha Lee nakha tell silica concentrations, there are 250 M, adjust volume, 0.002 ml methanol. 2.2 prepare a Stock solution of an aluminium concentration 0.003 M from complex substances aluminum (III) egmore, Chennai city had a rotno haidaret by reaction with acids. 3-CD-2-hydro investigated naphtha Lee nakha tell silica concentrations 0.0001 M DI water and 50% methanol over Norwich as a solvent. 2.3 p.a. with highest range 4.50 ± 0.05, with λ excitation and emission 366 nm 460 NM. Used for measuring the quantity of the substance, for example, the following. No need to adjust seasoning. 2.4 the standardized aluminium 2.4.1 aluminium Stock from any solution 5.00 mL bottle size in volume-10.00 mL adjust the pH in the range of 4.50 ± 0.05 using 0.1 M of acetic/1 ml acetic buffer with Tehran. 2.4.2.0.0004 M acid 3-CD-2-hydro investigated LEE asked nakha naphtha silica 1 ml adjust the volume with water, shake until the tick volume, DI said, is 10 minutes to make sure polylactic. 2.4.3 brings to light intensity values measured by a meter that λ excitation full roll of 366 nm 460 nm emission and.3. chemical analysis of the samples. 3.1 Introduction solution examples in each section. Additional 0.0001 M acid 3-CD-2-hydro investigated LEE asked nakha naphtha silica, have more than enough, shake it for 10 minutes to make polylactic completely. 3.2 adjusting the APA chahai in the range of 4.50 ± 0.05 using 0.1 M of acetic/1 ml acetic buffer with Tequila, and adjust the volume with the volume of water is DI 25.00 mL. 3.3 apply, for example, milk powder and milk station foe Wright 7 best light intensity measured by the machine full of romance meter. Λ excitation at 366 nm 460 nm emission and4. the spiked sample analysis 4.1 brings a solution, for example, milk powder and milk sections, 4 3 Wright State the remaining foe made Spike Standard Addition Method fills a standard solution aluminum concentrations at 27 maikhrokram per liter. (Ppm) adjust the volume with volume 25 ml with DI water, shake it for a period of 10 minutes. 4.3 bring to light intensity measurement by means of the call with full specs on the metric rose and absorb light measurement using a graphic-Ness whose Atomic furnish phosop 1980s. Specification of the year to find the perfect flavor. 4.4% for recovery (criteria for acceptance of 90-100%) and compare the concentration of aluminium in the sample found in one of two ways:
