A simple analytical procedure is proposed for simultaneous determination of three common dyes (Basic Blue 9, Brilliant Blue E-4BA, and Reactive Blue 2) in natural waters without prior separation of the solutes. A popular chemometric method, partial least squares regression PLS-1, was effectively applied for spectral resolution of a highly overlapping system. At the best modeling conditions, mea...

Three different reactive dyes Reactive Blue 19, Reactive Orange 16 and Reactive Red 180 were dissolved in water separately in concentration 0.04g/l as model pollutants for contaminated wastewaters from textile industry. Every wastewater sample was treated by ozone with concentration 2000 ppm for 30 minutes at ambient temperature and the effect of discoloration was traced after 5, 10, 20 and 30 ...

    Background & Aims of the Study: Textile wastewaters are very various in chemical qualities. In other words, these industries are one of the largest producing dyes compounds; therefore their treatment is so complex and difficult. The aim of this study was to evaluate the potential removal of Reactive Red 198 and Blue Reactive 19 from synthetic solution by Acaciatortilis shu...

رنگ ها مواد آلی سمی با ساختار پیچیده ای هستند که یکی از عمده ترین آلاینده های محیط زیست محسوب می شوند. اینمطالعه در تابستان و پاییز 94 در شهرستان بندرعباس با هدف بررسی امکان سنجی استفاده از ذرات کیتوزان به عنوان بیوجاذب درجذب رنگ Reactive blue 4 از محلول های آبی و بررسی ایزوترم و سینتیک جذب انجام گردید. این مطالعه تجربی به صورتناپیوسته انجام و اثر پارامترهای زمان تماس، pH ، غل...
