In this presentation, research, development of new methods for the Quantitation of Pb. By using nano-particles in the synthetic method of chemical levels green (GREEN CHEMISTRY) by Nano-particle synthesis in level with the way light ridakchan process is environmentally friendly and use a polymer that has a negative charge is a polymer acrylic aesit (TA Polymethacylic acid sodium salt. : PMA) as a non-signature on each stabilize pH is equal to 4.75 to furnish is recognized by this method relies on the reaction between complex compound ethylene acetic aesit learn more, adidas has occupied totra (EDTA)-silver nano-particles in aqueous solution with lead levels. A yellow complex compound by increasing proper is made of complex compounds such as wave length max. A battery range is a straight line. The lower limit for checking measurements and minimum in measuring the percent return and found up to a maximum equal to absorb light, 507 nm has a charge equal to the standard graph-is 22.47. concentration on measuring and minimum in a complex investigation that concentration 1.0-1000 mg/l. There is a linear equation, y = to decrease is equal to 0.0001 x + 0.041 correlation coefficients (r2) equals 0.999 this is the lower limit in measuring (3SD) and the minimum quantity that can be quantitative measurement (10SD) equal to 46.47 and 154.92 mg/l, respectively, and the team returned to percent.In this method, the range to which to apply a chemical analysis technique by sensors on the paper by testing the accuracy of the method by increasing proper is made of complex compounds such as range in a straight line. The lower limit for checking measurements and minimum in measuring and per cent were graph returns found that the standard range is concentrated on measuring and minimum in a complex investigation that concentration 10-1000 mg/l. There is a linear equation, y is equal to decrease = 0.029 x + 112.72 value correlation coefficient (r2) with this method limits 0.8879 minimum measuring (3SD) and the minimum quantity that can be quantitative measurement (10SD) equals 141.7 mg per liter and 177, respectively, and were to be put back in the range which can be applied to 127.35 161.32 actually works in the field. Reducing the use of chemicals and glassware and therefore suitable for use in developing countries is especially important.Keywords: Green Chemistry process, Nano-Silver particles ridakchan light levels through analyzing on paper.
