The change of standard Gibbs energy of solubilization (ΔG s o) for all of the additives was found to be negative. The values of change of standard enthalpy (ΔH s o) and that of standard entropy (TΔS s o) values were found to depend on the type and chemistry of the additive. The results were explained on the basis including chemistry of additives, their effect on water structure, and solubilization of additives either in the micellar or in aqueous phases.  ISSN : 1061-933X  Journal Name : Colloid Journal  Volume : 74  Issue Number : 1  Publishing Year : 1433 AH 2012 AD  Article Type : Article  Added Date : Saturday, February 11, 2012  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email شعيل أحمد الثبيتي AL-Thabaitia, Shaeel Ahmed Researcher Doctorate sthabiti@hotmail.com عبدالله يوسف عبيد Obaid, Abdullah Yousif Researcher Doctorate aobaid@kau.edu.sa ضياء أحمد خان Khan, Ziya Ahmad Researcher Doctorate ziyaakhan@gmail.com Tanweer Ahmad Ahmad, Tanweer Researcher Doctorate   Arniza Ghazali Ghazali, Arniza Researcher Doctorate   Kabir ud-Din ud-Din, Kabir Researcher Doctorate   Files File Name Type Description  32251.pdf pdf Abstract Back To Researches Page
