A microwave-based procedure for arsenic species extraction in alga samples (Sargassum fulvellum, Chlorella vulgaris, Hizikia fusiformis and Laminaria digitata) is described. Extraction time and temperature were tested in order to evaluate the extraction efficiency of the process. Arsenic compounds were extracted in 8 ml of deionised water at 90 °C for 5 min. The process was repeated three times...
The use of portable X-ray fluorescence (PXRF) and inductively coupled plasma atomic emission spectrometry (ICP-AES) increases the rapidity and accuracy of soil contamination mapping, respectively. In practice, it is often necessary to repeat the soil contamination assessment and mapping procedure several times during soil management within a limited budget. In this study, we have developed a ra...
ثابت شده که بارناکل ها یک وسیله مناسب برای پایش فلزات سنگین می باشند. بارناکل balanus amphitrite (crustacea: cirripedia) و رسوب از 5 ایستگاه واقع در آب های ساحلی بندر امام خمینی(ره), ایران, در طی دو فصل زمستان 87 و تابستان 88 جمع آوری شدند. انتخاب ایستگاه ها به گونه ای بود که اولا کل اسکله های بندر را تحت پوشش قرار داده دوما تاثیر فرایند های مختلف کشتیرانی و همچنین صنایع مختلف واقع در بندر، مور...
Analysis of Kemps and Land O’Lakes brand 2% milk was performed to detect aluminum, magnesium and calcium levels. ICP-AES was utilized because of its quick run time and ability to detect all three elements simultaneously. Mg and Ca levels were found to be well below expected values and Al was in too small a concentration to detect using this method. A possibility for the low results was that the...
The evaluation of the Gd-carborane complex 2 as an MR imaging and boron carrier agent was carried out in vivo using tumor-bearing Donryu rats, MRI, ICP-AES, and alpha-autoradiography. The MR imaging revealed that the carborane Gd-DTPA 2 was metabolized slower in the body than Gd-DTPA 1. The results of the ICP-AES method indicated that compound 2 was incorporated into normal tissues and metaboli...
Determinations of boron in animal tissues were performed by introduction technique for the determination of trace levels of B by ICP-AES. inductively coupled plasma atomic emission spectrometry (ICP-AES) with an ultrasonic nebulizer. The method is based The accurate determination of B in animal tissues has proven di cult because of the very low concentrations found in some on the microwave dige...
