Abstract EN
Waste petroleum deposits (WPD), collected from the heat exchanger of naphtha hydrotreater unit were shown to be an effective, low-cost sorbent for the removal of Pb2+ and Zn2+ ions from aqueous solution.
WPD were characterized by CHN, IR and ICP - Elemental analysis.
Batch experiments were conducted to known the influence of various parameters of adsorption on the removal of Pb2+ and Zn2+, including adsorbent dose, ph, contact time as well as the metal concentration were separately investigated.
Based on the obtained results, it has been found that the % of adsorption increase with an increase in ph to reach 95.3 and 97.9 % for Pb2+ and Zn2+ ions at ph s 4.6 and 6.1 respectively.
The adsorption data was described by Langmuir, Freundlich, and BET adsorption isotherm model.
The qmax obtained from the three models for Pb2'+ were 41.2, 21.6 and 339.96 mg/g respectively.
While qmax values for Zn2+ were 9.83, 2.8 and 3.35 mg/g by Langmuir, Freundlich and BET isotherm respectively.
The regression coefficient (R2) was 0.99 by Langmuir and BET isotherm in the case of Pb2+.
While was 0.98 and 0.97 for Zn2+ respectively, which specifies that the type of adsorption of metal ions on WPD was chemo-sorption characterized by strong attractiveness.
The test results indicate that WPD could be used as a low-cost adsorbent for the removal of Pb2+ and Zn2+ from aqueous solution
