چکیده
روش میکرواستخراج مایع-مایع پخشی کمک شده با آلتراسونیک بر اساس مایع یونی برای تعیین مقادیر ناچیز یون های Rh3+از محلول های آبی بکار گرفته شد تا یک روش آماده سازی سریع و معتبر برای تعیین یون های Rh3+ به روش اسپکتروفتومتری ارائه گردد. یون های Rh3+ با استفاده از واکنشگر کمپلکس دهنده 5-(4-کلروفنیل آزو)-6-هیدروکسی-پیریمیدین-2و4 دی ان (CPAHPD) و با استفاده از یک حمام آلتراسونیک با مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم بیس (تری فلوئورومتیل-سولفوئیل) ایمید برای استخراج آنالیت در دمای اتاق مورد استفاده قرار گرفتند. 250 میکرولیتر اتانول به فاز غنی از مایع یونی، بعد از سانتریفیوژ کمپلکس رودیم اضافه شده تا تشکیل قطرات مایع یونی را قبل از آنالیز اسپکتروفتومتری بهبود بخشد. در آخر تاثیر پارامترهای مختلف بر روی بازیابی یونی Rh3+بررسی و بهینه گردید. تحت شرایط بهینه، منحنی کالیبراسیون در محدوده 260-10 نانوگرم بر میلی لیتر خطی بوده و حد تشخیص 3.2 نانوگرم بر میلیلیتر با انحراف استاندارد نسبی 1.78± بدست آمد. مقایسه ی این روش با سایر روش ها، خطر تماس با حلال های سمی را کاهش داده ضمن اینکه نیاز به یک زمان استخراج کوتاه تری را لازم دارد. این روش بطور موفقیت آمیزی برای آنالیز نمونه های حقیقی بکار گرفته و با روش GF-AAS مقایسه گردید. روش پیشنهادی بطور موفقیت آمیزی برای آنالیز و با روش ETAAS مقایسه گردید.
