Abstract

Pollution of the environment with toxic metals is widespread
including wastewater. Lead is the most element concerning health
and environment due to its accumulation potential in the food chain
and also in ground water. The aim of this research was to study the
adsorption ability of five different natural materials such as (Cotton
stalks, Acacia, Orange peels, Rice straw and Pomegranate peels) for
removal of lead ions from lead polluted solution and industrial
wastewater and the effect of water remediation on the growth of
sunflower plants.
Lead polluted solution (200 ppm Pb) was treated with the
different portions of natural materials i.e. 0.25, 0.5 and 1 g/100 ml.
Residual concentration of lead in the solution was measured after
24, 48 and 72 h. lead concentration was decreased after 72h using
cotton stalks, acacia, orange peels, rice straw and pomegranate peels
from 200 ppm to 1.07 (89.3%), 1.45 (85.5%), 1.20 (88%), 0.85
(91.5%) and 0.54 (94.6%), respectively. A Pot experiment under
greenhouse conditions in a virgin soil was conducted in to
determine the effect of water remediation on the growth of
sunflower plants (Helianthus annuus cv. Avante) and was irrigated
using industrial wastewater collected from Helwan iron and steel
industries. Data indicated that irrigation with industrial wastewater
inhibited seed development, reduced seed oil percentage, crude
proteins percentage, increased total carbohydrates and the mobility
of lead within the plant compared with the treatments of remediated
water and control. It was declared that, water remediation decreased
the plant hazard caused by lead present in industrial wastewater.
