چکیده

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.
