15 صفحه اولComparison of three procedures (single, sequential and kinetic extraction) for mobility assessment of Cu, Pb and Zn in harbour sediment
The mobility of Cu, Pb and Zn in harbour sediments was investigated using single, sequential and kinetic extraction techniques. Each type of extraction provides different information on the mobility of these elements in the environment. The single HCl extraction assesses general mobility, the sequential extraction assesses geochemical partitioning and kinetic extraction allows quickly and slowl...
متن کاملMonitoring of Heavy Metals Contamination (Pb, Zn, Cr and Cu) in Sediments of Balkhlou River of Ardebil by Implication of Sediment pollution Indices
Background: Water contamination of heavy metals is one of the major threats to human health and food chain. In this study, concentration of heavy metals of lead, chromium, copper and zinc in sediment was measured in order to assess their ecological effects and their risk. Methods: To determine the concentration of metals, 12 stations were selected along the river and 3 samples from the sedi...
متن کاملAnthropogenicimpacts on heavy metals (Pb, Ni, Zn and Fe) concentration in surface sediments of Shoor River Estuary, Bandar Abbas
Toxicity of trace metals in the environment, bioaccumulation in aquatic environments and in food chains are of great importance.This study concentrates on the distribution patterns of some heavy metals (Pb, Ni, Zn and Fe) in surface sediments of Shoor River estuary to obtain an overall classification for the origins of the metals in the studied area. In order to determine the degree of Contamin...
متن کاملextraction and characterization of allium irancum plant extract and its application in the green synthesis of silver nano particles and oxidation of thiocarbony1 compounds
سنتز سبز نانوذرات فلزی (nps) درسالهای اخیر توجه بسیارزیادی را به خود جلب کرده است. زیرا این پروتوکل کم هزینه وسازگار با محیط زیست از روش های استاندارد سنتز. در این پایان نامه ما گزارش میکنیم یک روش ساده و سازگار با محیط زیست برای سنتز نانوذرات نقره با استفاده از محلول آبی عصاره گیاه allium iranicum به عنوان یک عامل کاهش دهنده ی طبیعی. نانو ذرات نقره مشخص شد با استفاده از تکنیک های uv-visible، x...
