چکیده

در مقاله حاضر از روش مشتقی پیک تا پیک طیف نسبی به منظور تعیین غلظت اجزای مخلوط‌های مختلف دوتایی از سه رنگزا با رنگ‌های زرد، سرخ و قرمز استفاده گردید. در روش مشتقی پیشنهادی، از اختلاف مقادیر طیف جذبی نسبی به دست آمده در دو اکسترمم همسایه ( مقدار پیک تا پیک) جهت پیشگویی غلظت مواد رنگزا استفاده شد. مقادیر متوسط فاکتور بازیابی، خطای مطلق و خطای نسبی پیشگویی غلطت در نمونه‌های مختلف دوتایی تهیه شده در این تحقیق با استفاده از روش معمول به ترتیب 82/112، 00622/0 و 693/22 و با استفاده از روش مشتقی ارائه شده 287/99، 00033/0 و 118/1 بوده‌اند. با توجه به نتایج حاصله، روش مشتقی پیک تا پیک طیف نسبی در پیشگویی غلظت اجزای مخلوط‌های دوتایی مواد رنگزا نسبت به روش معمولی از دقت بالاتری برخوردار است.

چکیده [English]

In the present work, ratio spectra derivative method (p-p) was used in order to determine the dye contents in different bicomponent dye mixtures prepared with three dyes of yellow, scarlet and red colors. The difference between neighboring extremmum values at derivative ratio spectra of bicomponent mixtures of the dyes were used for determination of dye content. The obtained recovery factor, absolute error and relative error by using the proposed derivative technique and normal methods were 99.287, 0.000033, 1.118 and 112.82, 0.00622, 22.693 respectively. The analysis of obtained results via the proposed derivative and normal methods show higher accuracy of the developed method in determination of bicomponent dye solutions.
