Abstract

The objectives of the current investigation aimed to a) assess the
ability of sorghum plants (Sorghum Bicolor L.) to accumulate
cadmium in its tissues (phyto-remediation) and b) compare the
efficiency of phyto-remediation and chemical method to extract Cd from
either Cd-contaminated water-culture or sandy clay loam calcareous
soil. To achieve these objectives, three experiments were conducted, i.e.,
a) nutri-culture experiment (water-culture), b) green pot experiment using
a calcareous soil and c) sequential extraction experiment (laboratory
incubation). Cd was applied at the rates of 0, 1 and 2 mg L-1 in the waterculture experiment; and 0, 100 and 200 mg kg-1 in the green pot
experiment.
The obtained results indicated that dry matter yield of sorghum plants
decreased in both the water-culture and pot experiments vs increasing its
concentration and uptake in plant tissues with increasing the applied Cd
rate. Sequential extraction showed that removal amounts of Cd by
ammonium bicarbonate-DTPA (AB-DTPA) as well as ammonium
acetate-EDTA progressively increased with increasing Cd rate from 100 up < br />to 200 mg kg-1 soil. Percent removal of Cd by 1st extraction was greater than
the 2nd one using either extractant. AB-DTPA extracted about 18 % which
nearly double of contaminating Cd by AA-EDTA (about 7 %)
