Abstract
ABSTRACT The paper reports Boron (B) uptake using Leucaena leucocephala seed pods (LLSP) as a pre-treatment for reverse osmosis seawater desalination. The process increases the quality of the membrane-entering nutrient water. The research investigated a new, low-cost biosorption technique for boron from Gaza shore on the Mediterranean Sea at a distance of 300 m from shore and 1 m deep. The maximum adsorption efficiency reached 85.7% at pH 12, 30 min contact time, and adsorbent dosage of 2 g/100 ml seawater. The initial and final concentration of boron was measured using Inductively Coupled Plasma (ICP). The Langmuir and Freundlich isotherms were applied to the adsorption data. The kinetic data for removal processes were fitted with the pseudo-second-order model.
