استحداث برنامج حاسوبي باستخدام ال Simplex Optimization لتحديد الطريقة الفضلى في قياس عنصر الكروم في الأنسجة الحيوية

الملخص EN

A computational investigation has been used to chose the best acid which gave the real concentration of chromium in Certified Reference Material (C.R.M) type (MA-A1) (known concentration of chromium).

A concentration of chromium which obtained from the Atomic Absorption Spectroscopy (AAS) of (C.R.M) were input using Mathlab Ver.6.1 program and simplex optimization method.

The program was written and the condition of experiment such as (weight of substance, type of acid, dilution factor and the response of AAS) were input as a matrix.

In order to reduce the contamination of chromium which come from dust, tow conditions were input in the program , the first one is the comparison between the real concentration and the concentration which was obtained from AAS and the second one is to obtain the smaller concentration of chromium in the substance (C.R.M).

In this paper the results has been represented by one point on the curve (which is related to the absolute error as a function of the concentration for each acid ) depend on a such condition .

this curve gave a low absolute error using second order ordinary equation, the point showed that the (HClO4:H2O2)(1:1) is the best mixture for chromium analysis.

The computational results showed that its possible to measure concentration of other elements for different source and hens deferent input conditions depend on such experiment using this new program.
