| description | Olive industries generate olive stone waste (OSW), which is recognized as an organic contaminant. Jordan is one of the Mediterranean Sea countries that produces a large amount of these residues. Waste from olive stones could serve as a biosorbent. One of the most hazardous heavy metals produced in a variety of industries, including the production of paint and batteries, is lead ions. The purpose of this work is to remove lead ions using olive stone waste as a biosorbent by adsorption techniques. The effects of initial concentration, pH, adsorbent concentration, and contact time are covered in the first section of the adsorption parameters, which is comprised of batch studies. In the second section, the breakthrough curve study was carried out using a fixed bed adsorption column. Findings said that the ideal pH for highest removal efficiency was occurred at 6.8 acidity and the most promising removal efficiency, at 25 ± 2 °C and 1 g of adsorbent for every 0.25 L of solution, hit 82.5 % of the initial concentration of 9 mg/L while 1 g of adsorbate was adsorbed in 1.9 mg of adsorbent. The breakthrough study indicated that after 110 h of operation a 150 L of treated solution attained with maximum removal efficiency of 90 % for lead ions initial concentration of (18 mg/L). |
