First the oil needs to be released from the surface

This preview shows page 4 - 6 out of 9 pages.

First the oil needs to be released from the surface it is resting on. Wetting is the first stage as the detergent undermines the oil-surface attraction and starts displacing the oil into droplets. The process is accelerated at higher temperatures تيتشتلا Dispersion تارطقل اهليوحت نم ً لدبةبلصلا تائيزجلا قيلعتو تيتفت ىلع يوطني هنأ لإ ، بلحتسلا لثم تويزلا لثم . Similar to emulsification except it involves the breaking up and suspension of solid particles rather than fluid droplets. ةباذلا Solubilisation .( ) ةيلمعلا هذه رصتقت تتشتلاو بلحتسلا نع فلتخت لولحم يلا تايافنلا ليوحتو ذخأ متي ءاملا يف ةبئازلا تايافنلا يلع . This is taking up of soil components into a true solution (rather than emulsification or dispersion). This may relate to water soluble soils. يئاملا للحتلا Hydrolysis . ةريغص ةيعرف تادحو نم ةريبكلا تائيزجلا هذه نوكتت تارديهوبركلاو تانيتوربلاب طبتري اذه تائيزج قلطإ يلاتلابو رغصلا هتادحو ىلإ ءيزجلا ميسقت ىلع يئاملا للحتلا يوطنيو ، . مدختستو ، ىوصقلا ةضومحلا ةجرد يف ربكأ ةعرسب ثدحي ءاملا يف نابوذلل ةلباق رغصأ . ضرغلا اذهل ضامحلاو تايولقلا This relates to proteins and carbohydrates. These large molecules are made up of small subunits Hydrolysis involves splitting the molecule at the joints into its smaller units and thereby releasing smaller water soluble molecules. It takes place most rapidly at extreme pH, and alkalis and acids are used for this purpose.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
