Ability of some crops for phytoremediation of nickel and zinc heavy metals from contaminated soils
The present study was aimed at comparing the ability of three crop plants for phytoremediation of zinc (Zn) and nickel (Zn) from soils. A factorial (3×2×3) experiment based on RCBD was used to compare the treatments, and was repeated three times. The first factor was crop type (wheat, clover and rapeseed), the second factor was heavy metal types (zinc (Zn) and nickel (Ni)) and the third factor ...
متن کاملNitrogen and carbon dioxide adsorption by soils.
High-resolution nitrogen (77 K) and carbon dioxide (273 K) adsorption at subatmospheric pressures has been studied for a range of model soils of various origins with different organic matter (OM) contents. It is demonstrated that N2 and CO2 molecules probe different regions of soil particles. Nitrogen is adsorbed primarily on the outer surface of soil particles, while CO2 has a higher affinity ...
متن کاملPhosphate adsorption by ferrihydrite-amended soils.
New technology and approaches for reducing P in runoff from high sediment yield areas are essential due to implementation of increasingly rigorous water quality standards. The objectives of this research were to characterize ferrihydrite (Fe(5)HO(8).4H(2)O) in terms of its ability to adsorb P from soil solutions and relate its P adsorptive capacity to several soil properties that influence P mo...

ویژگی های زمین شیمیایی، کانی شناسی، و میکرومورفولوژیکی خاک ها و سنگ مادر مربوطه در منطقه بین بخش های جنوبی زاگرس و خلیج فارس تا دریای عمان(استان هرمزگان، ایران) مورد بررسی قرار گرفت. هدف های این مطالعه شناسایی تغییرات در خصوصیات فیزیکی، شیمیایی، و ترکیب کانی شناسی خاک، مطالعه میکرومورفولوژی و تکامل خاک، و بررسی توزیع عنصر خاک بر اساس هوازدگی، پروسه های خاک و زمین شناسی جهت توصیف اثرات مواد مادر...
15 صفحه اولChemical Fractionation of Cadmium, Copper, Nickel, and Zinc in Contaminated Soils
Heavy metals are potentially toxic to human life and the environment. Metal toxicity depends on chemical associations in soils. For this reason, determining the chemical form of a metal in soils is important to evaluate its mobility and hioavailability . Sequential extraction was used to fractionate four heavy metals (Cd, Cu, Ni, and Zn) from nine contaminated soils into six operationally defin...
