The latter showed a change in its colour upon changing the pH of the solution. The sensitivity of these molecules was clear in the pH range of 6-11. All four dyes start to show change in thiere visible spectra when the pH starts to reach the basic range.  ISSN : 1319-1012  Journal Name : Journal of King Abdulaziz University  Volume : 21  Issue Number : 1  Publishing Year : 2009 AH 2009 AD  Article Type : Article  Added Date : Sunday, January 31, 2010  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email خيرية الاحمري Al-Ahmary, Khairia Researcher Doctorate   خديجة الزايدي Al-Zydi, Kahadija Researcher Doctorate   Abdullah محمد عسيري Asiri, عبدالله Mohamed Researcher Doctorate aasiri2@kau.edu.sa Files File Name Type Description  24955.pdf pdf Abstract Back To Researches Page
