Assessment of Phytoremediation Potential of Alyssum Maritimum in Remediation of Lead-Contaminated Soils
Background and Aim: Phytoremediation is a promising method for improving soils that can easily absorb heavy metals, resulting in decontamination of the soil. The objective of this study was to assess the phytoremediation potential of Alyssum maritimum in the remediation of lead-contaminated soil. Materials and Methods: A randomized complete block design was used with five levels of lead (Pb) c...
متن کاملFly Ash Amended Soils as Highway Base Materials
Class F fly ash cannot be used alone in soil stabilization applications as it is not selfcementing. An activator such as Portland cement or lime must be added to produce cementitious products often called pozzolan stabilized mixtures. The developed mixture must possess adequate strength and durability, should be easily compacted, and most importantly should be economical and environmentally fri...
متن کاملLeaching Behavior of Petroleum Contaminated Soils Stabilized with High Carbon Content Fly Ash
Utilization of recycled materials as a substitute for natural soils in engineering applications such as highway construction is an emerging application area. A research study was conducted to investigate the stabilization of petroleumcontaminated soils (PCSs) using another recycled material, high carbon content fly ash (HCCFA), and evaluate the feasibility of using the final product in highway ...
متن کاملBiological responses of agricultural soils to fly-ash amendment.
The volume of solid waste produced in the world is increasing annually, and disposing of such wastes is a growing problem. Fly ash (FA) is a form of solid waste that is derived from the combustion of coal. Research has shown that fly ash may be disposed of by using it to amend agricultural soils. This review addresses the feasibility of amending agricultural field soils with fly ash for the pur...
متن کاملUtilization of nSiO2, fly ash, and nSiO 2/fly ash composite for the remediation of triphenyltin (TPT) from contaminated seawater.
The removal of triphenyltin chloride from contaminated simulated seawater with adsorption method was discussed. The adsorbents used are fly ash, nSiO2, and nSiO2/fly ash composite. The results showed that the adsorption of the adsorbents increases with increase in the adsorbent dose, contact time, pH, stirring speed, initial TPT concentration, and decreased with increase in temperature. The ads...
