A novel functionalized mesoporous silica based meso adsorbent was prepared for simple, efficient and rapid determination, sorption and recovery of trace palladium(II) in wastewater. The meso adsorbent was prepared by indirect immobilization of ((3(3(methoxycarbonyl)benzylidene)hydrazinyl)benzoic acid) onto the cage pored mesoporous silica. The optimum conditions were measured as a function of solution acidity, contact time, ion selectivity and adsorption isotherms models. The data revealed that meso-adsorbent offered simple and one step procedure without using high tech instruments. The determined detection limit and sorption capacity were 0.11 ppb and 184.50 mg/g, respectively. The meso-adsorbent can be repeatedly recycled without deterioration of the unique mesostructures and maintaining the same functionality for detection/sorption operations in next uses.
