| Summary, etc. | The aim of the present research is to study the effect of adsorbents, activated charcoal and water hyacinth roots, on the removal efficiency of heavy metals, Pb, Fe, Cu and Cd, by using laser induced breakdown technique (LIBS) under different depths, contact time and initial concentration. Synthetic stock solutions of heavy metals were prepared. The used depths were 20, 40, 60 and 80 cm. the contact times were 20, 40, 60, 80, 100 and 120 min. the concentrations of heavy metals used in this study were 100, 200, 300 and 400 mg/L. The obtained results revealed that, removal efficiency of charcoal for Pb, Fe and Cu when the initial concentration increased from (100 to 400) mg/L, the removal efficiency increases from (81.13 to 92.10) %, (70.33 to 73) % and (71.33 to 72.67) % respectively. While it deceased for Cd from (23.67 to 21.33) %. The obtained results revealed that, removal efficiency of dried roots of water hyacinth for Pb, Fe and Cu when the initial concentration increased from (100 to 400) mg/L, the removal efficiency increases from (69.23 to 77.96 %), (54.54 to 55.67) % and (44.89 to 46.84) % respectively. While it decreased for Cd from (11.44 to 11.24) %. The effect of charcoal on maximum removal efficiency of the studied heavy metals was between 93 %, 74, 73.67 and 24.33 % for Pb, Fe, Cu and Cd in depth 80 cm respectively. In addition, water hyacinth also effect on the maximum removal efficiency for the same heavy metals studied and it was between 93 %, 74, 73.67 and 24.33 % for the same depth. LIBS technique is utilized to measure the effect of charcoal and water hyacinth on Removal efficiency of the studied heavy metals Pb, Fe, Cu and Cd. Removal efficiency increases with time and reaches a maximum from 60 to 80 min of contact time for charcoal, contracting water hyacinth it was 100 and 120 min. It was found that the removal efficiency of charcoal and water hyacinth for following elements Fe, Cu, Pb and Cd are affected by the initial concentration. Statistical analysis with ANOVA (F test) reveals that the data presented not only reveals that all treatments have significant difference for all studied concentrations 100, 200, 300 and 400 mg/L between removal efficiency means but also for all depths and times. The T-Test shows that the data presented significant differences, the removal efficiency of all charcoal treatments contained a large value compared of those of all water hyacinth treatments for Pb, Fe, Cu and Cd. The studied heavy metals can be arranged due to their removal efficiency on the following descending order Pb > Fe > Cu > Cd |
