The uptake of nickel and copper from water by Apium nodifolium (L.) Lag.

Abstract

Heavy metal pollution is a major environmental problem the modern world. The most commonly used methods for dealing with heavy metal pollution are still extremely costly. These methods have different efficiencies for different metals and may be very costly if large volumes, low metal concentrations, and high cleanup standards are involved. The use of metal-accumulating plants to clean soil and water contaminated with toxic metals is the most rapidly developing component of this environment friendly and cost-effective technology. The removal of Cu (highest BCF= 1614) and Ni (1116) from water was studied using different Ni and Cu exposure levels in laboratory by macrophyte, Apium nodifolium (L.) Lag. The uptake rate of Cu and Ni increased, when the exposure time came longer and the initial concentration was lower. © 2016 Innovative Scientific Information & Services Network. All Rights Reserved.
