Abstract EN
Phytoextraction is an effective and environment-friendly approach for remediation of soil polluted with toxic metals.
Portulaca oleracea is a potential hyperaccumulator of Cr(VI) from polluted soil.
In this study, the effect of soil organic content, pH, and sulphate concentration on phytoextraction of Cr(VI) using Portulaca oleracea was investigated.
Seedlings of Portulaca oleracea were grown in soils with (i) three organic content compositions, (ii) six levels of pH, and (iii) six concentrations of sulphate salts; all were irrigated with Cr(VI) solutions at 200 ppm concentration.
Chromium concentration in different tissues of plants was monitored under the variant conditions.
Results indicated that the uptake of Cr(VI) by Portulaca oleracea is favoured at (i) low organic content soil (0.42%), (ii) slightly alkaline pH range (∼8), and (iii) with sulphate concentration in the range of 300–600 ppm.
