Abstract AR
تم تطبيق طريقة قياس جهد النبض التفاضلي لتفكك المصعد (DPASV) لتحليل آثار Pb2+, Cd2+, Cu2+ في التربة الزراعية و تم استخدام رقاقة زئبق على كربون زجاجي (TMFGC) كقطب للعمل و تم استخدام خلية كهروكيميائية ثلاثية القطب يتم التحكم بواسطة الحاسب الآلي لضبط جهد التحلل الكهربي.
كما تم ضبط التركيز بطريقة الإضافة القياسية.
و كانت أفضل قيمة للرقم الهيدروجيني لمحاليل Pb2+, Cd2+, Cu2+ تعطي نتائج جيدة هي 3.2، 4.6 و 3.6 على الترتيب.
و دلت النتائج التي تم الحصول عليها أن طريقة DPASV يمكن أن تستخدم بشكل فعال لتقدير Pb2+, Cd2+, Cu2+ في التربية الزراعية.
Abstract EN
The method of Differential Pulse Anodic Stripping Voltammetry (DPASV) has been applied for trace analysis of Pb2+, Cd2+ and Cu2+ in agricultural soil.
Thin mercury film on glassy carbon (TMFGC) was used as the working electrode.
A computer controlled three electrode-electrochemical cell was used for control potential electrolysis.
Standard addition method was applied for concentration calibration.
The optimum pHs of the solutions of Pb2+, Cd2+ and Cu2+ to obtain reproducible results are 3.2, 4.6 and 3.6 respectively.
The results obtained in this study indicate that the method of DPASV can effectively be used for quantification of Pb2+, Cd2+ and Cu2+ in agricultural soil.
