| چکیده | ||
| In this work, a microextraction technique based on pipette tip solid-phase extraction was used for preconcentration and determination of diazinon. Carbon nanotube functionalized by zinc sulfide and ethylene glycol was used as sorbent. Determination of diazinon was performed using high performance liquid chromatography and UV detection. Important parameters that influence the extraction efficiency (i.e. pH, amount of adsorbent, extraction time, salt addition, volumes of sample and eluting solvent and number of aspirating/dispensing cycles for both solvent and sample) were investigated and optimized. Results were showed that method was validated over the range of 0.50 - 100.0 µg L-1. Repeatability was satisfactory, bellow 3.78% for 5 replicate measurements of 20 µg L-1 of diazinon. The limit of detection of this method is 0.03 µg L-1 with an enrichment factor of 100 and short extraction time of 8.5 min, which confirmed suggested method is a reliable and accurate for extraction and preconcentration of diazinon. | ||

| چکیده [English] | ||
| در این تحقیق یک تکنیک میکرواستخراج بر پایه استخراج فاز جامد بوسیله سرسمپلر برای پیشتغلیظ و تعیین مقدار دیازینون استفاده شد. نانولولههای کربنی توسط سولفید روی و اتیلن گلیکول عاملدار شد. دیازینون توسط دستگاه کروماتوگرافی مایع با عملکرد بالا تعیین مقدار شد. پارامترهای مهم مانند pH، مقدار جاذب، زمان استخراج و اثر نمک، حجم حلال و حجم محلول و تعداد دفعات پر و خالی کردن سمپلر که بر بازده استخراج مؤثر بودند، بهینه شد. نتیجه نشان داد که این روش برای گستره 0.5 تا 100 میکروگرم بر لیتر خطی است. تکرارپذیری روش رضایتبخش است و زیر 3.78% میباشد و حد تشخیص و فاکتور تغلیظ روش 0.03 میکروگرم بر لیتر و 100 بدست آمد که درستی روش را در تعیین دیازینون تأیید میکند. | ||
