In this study, the quantitative analysis of heavy elementals contents available in drinking water are studied using one step technique; laser induced breakdown spectroscopy (LIBS) technique. This was done by developing a new method to improve the detection limits of LIBS for manganese (as example of heavy elements) in aqueous solutions with different concentrations. In this method a medium-density fiberboard (MDF) wood have been used as a substrate that absorbs the liquid sample to transform laser liquid interaction to laser solid interaction.

Copper concentrations in drinking-water is very important to be monitored which can cause cancer if it exceed about 10 mg/liter. In the present work, we have developed a simple, low laser power method to improve the detection limits of laser induced plasma spectroscopy LIBS for copper in aqueous solutions with different concentrations. In this method a medium density fiberboard (MDF) wood have been used as a substrate that absorbs the liquid sample to transform laser liquid interaction to laser solid interaction.

تعتبر تقنية القياس الضوئي ميدانا واسعا لإمكانية استخدام الظواهر الضوئية وخواص الضوء المختلفة للحصول على معلومات عن جسم ما. تتضمن الظواهر الضوئية عادة تفاعل الضوء مع الوسط. قد يكون التفاعل خطيا يتضمن امتصاص أو انتشار أوتشتت، أوتألق أوتبعثر للضوء. توفر لنا خصائص الضوء من سعة و طور و استقطاب و طول موجي و سرعة في وسط ما ,عالما غنياً بالمعلومات. أما في حالة الظواهر الضوئية غير الخطية فتكون الشدة المرتفعة للضوء هي العامل الأساسي.
