Chelating agent is known as the enhancer for metal phytoextraction; however, there still a lack of efficient and environmentally sustainable chelators. Here, lemon residue extraction (LRE), prepared from 11 kinds fruit wastes, was combined with N, N-bis (carboxymethyl) glutamic acid (GLDA), tea saponin (T.S.) compounded plant-derived chelator (CPC), their influences on Cd phytoextraction by hyp...

Sorted and aged bottom ash from Waste-to-Energy plants, i.e., MIBA (the Mineral fraction of Incinerator Bottom Ash) are potential source metals that could be utilized to meet the increased demand society. In this work, sunflowers (Helianthus annuus) rapeseed (Brassica napus) were cultivated in conventional evaluate possibility for phytoextraction, mainly Zn, during period one cultivation season...

Abstract Purpose The increasing volumes of mine tailings that are being generated globally because the rise in metal demand, whilst ore-grades continue to decline, call for novel sustainable management options. Phytoextraction using hyperaccumulator plant species may be one such strategies deal with these large contaminated materials. However, base metals (such as zinc, lead, copper) inherently...

Phytoextraction is a remediation technology that uses plants to remove heavy metals from soil. The success of a phytoextraction process depends on adequate plant yield (aerial parts) and high metal concentrations in plant shoots. A pot experiment was conducted to investigate the combination effects of plants [sunflower (Helianthus annuus) and canola (Brassica napus)] with soil treatments (manur...
