Leaf Powder

Ficus benghalensisL., a plant-based material leaf powder, is used as an adsorbent for the removal of lead ions from aqueous solution using the biosorption technique. The effects of process parameters such as contact time, adsorbent size and dosage, initial lead ion concentration, and pH of the aqueous solution on bio-sorption of lead byFicus benghalensisL. were studied using batch process. The Langmuir isotherm was more suitable for biosorption followed by Freundlich and Temkin isotherms with a maximum adsorption capacity of 28.63 mg/g of lead ion on the biomass ofFicus benghalensisL. leaves.

AbstractThe present work investigates the performance of Ga-doped ZnO (GZO) and Ca-doped ZnO (CZ) nanopowders as an efficient nanomaterials for the removal of lead ions from aqueous solutions. The sol–gel method was used to synthesise the nanoparticles from zinc acetate dihydrate. To incorporate Ca and Ga in ZnO, adequate quantities of calcium chloride hexahydrate and gallium nitrate hydrate were added to ZnO, and supercritical drying conditions of ethyl alcohol were used. Different Ca and Ga concentrations (1, 2, 3, 4, 5 at.%) were used to synthesise CZ and GZO. The structural and morphological properties of the as-prepared nanoparticles were determined using X-ray diffraction and transmission electron microscopy. Batch-mode experiments were used to remove lead from aqueous solution and to determine the adsorption equilibrium isotherms of lead ions using ZnO doped by 3 at.% of weight of Ca (CZ3) and Ga (GZO3). The effects of temperature, contact time, and pH on the removal of lead ions from aqueous solution by CZ3 and GZO3 were studied.
