| Summary, etc. | In this study, ion paired formed between trimethyl-1-nonanaminium bromide (NTAB) as surfactant and ion pairing agent as PTA, PMA, TPB and RN have been used as electroactive material for preparation of modified carbon paste electrodes (MCPEs) selective to (NTAB). Type and content of the different ion pairs on the performance of MCPEs were studied. It was found that the best content was 9 mg of NTA-TPB, which gives the best nernstian slope value 59.40 ± 0.43 mV decade-1. This fabricated electrode exhibit suitable response to NTAB in a concentration range from 1.0x10−6 to 1.0x10-2 mol L-1 with lower detection limit of 1.0x10-6 mol L-1. The fabricated MCPE exhibit fast response time of about 5 s under working pH range of 2.0 - 8.5.<br/>Also, type and content of the different ion pairing agent on the performance of insitu CPEs were studied. It was found that the best content was 6 mg of Na-TPB, which gives the best nernstian slope value 58.40 ± 0.82, mVdecade-1. This fabricated electrode exhibit suitable response to NTAB in a concentration range from 1.0x10−6 to 1.0x10-2 mol L-1 with lower detection limit of 1.0x10-6 mol L-1. The fabricated ICPE exhibit fast response time of about 10 s under working pH range of 2.5 - 8.0. The results obtained were satisfactory with excellent percentage recovery comparable and sometimes better than those obtained by other routine methods for the assay. |
| 520 #3 - SUMMARY, ETC. | |
| Summary, etc. | في هذه الرساله تم دراسه أنواع وكميات مختلفه من الزوج الأيوني مثل (NTA-TPB) وقد وجد أن القطب الذي يحتوي علي 9 ملليجرام من (NTA-TPB) انه يعطي افضل قيمه للميل mV decade-1 59.40 ± 0.43<br/>كما انه تم دراسه أنواع وكميات مختلفه من عوامل الازدواج الأيوني مثل )الفوسفوموليبدك , الفسفوتنجستنك , الرينيكات , والصوديوم تترافينيل بورات. (وقد وجد أن القطب الذي يحتوي علي 6 ملليجرام من الصوديوم تترافينيل بورات, انه يعطي افضل قيمه للميل mV decade-1 58.40 ±0.82<br/>تم دراسه العوامل المختلفه التي تؤثر علي كفاءة الأقطاب التي تم تحضيرها بطرق مختلفة طبقا لنظام IUPAC وقد وجد أن الأقطاب المصنعه يمكن استخدامها بنجاح للتقدير الجهدي للماده محل الدراسه في المدي المستقيم للقطب المعدل بالزوج الأيوني والمدي المستقيم للقطب المحضر بعوامل الازدواج الأيوني هما mol L- 1 1.0x10-6 – 1.0x10-2 وتتمتع هذه الأقطاب بثبات حراري من 10-60 درجه مئويه .<br/>وقد تمت دراسة درجه الحموضه ووجد أن استجابه القطب المعدل بالزوج الأيوني لاتعتمد علي درجه الحموضه في المدي (2.0 - 8.5). بينما القطب المحضر بعوامل الازدواج الأيوني(تترا فينيل بورات) لاتعتمد علي درجه الحموضه في المدي2.5 – 8.0 .<br/>وقد تمت دراسة وقت الأستجابه ووجد أن استجابه القطب المعدل بالزوج الأيوني 5 ثواني. بينما في حاله القطب المعدل بعوامل الازدواج الأيوني , فان وقت الاستجابه كان 10 ثواني. ووجد أن الأقطاب لها حساسيه عاليه ل(NTAB) وتم استخدامها في التقدير الجهدي للماده. |
