An Eco-Friendly Process for Removal of Lead from Aqueous Solution

Abstract

The adsorption of lead (Pb II) ion on different types of synthesized zeolite was investigated. The BET surface area, total pore volume & average pore size distribution of these synthesized zeolites were determined by adsorption isotherms for N2, the surface area & total pore volume of their sources were found by adsorption isothermN2.The adsorption equilibrium was measured after 24h at room temperature ( The atomic absorption spectrometry was used for analysis of lead heavy metal ion, the obtained results in this study showed that the different synthesized zeolites were efficient ion exchanges for removing heavy metal, in particular, the modified zeolite from shale clay by oxalic acid.

Comparative lead adsorptions in synthetic wastewater by synthesized zeolite A of recycled industrial wastes from sugar factory and power plant

“…As a result, size of surface area and pore volume of ZCF had higher than ZBG whereas the pore size of ZBG had larger than ZCF. The previous studies reported that zeolite A materials exhibited the high surface area and pore volume with a small pore size resulted to the high adsorption capability [ 58 , 59 ], so it was possible that ZCF was higher lead adsorption than ZBG. For STD, size of surface area, pore volume, and pore size were 10.460 m 2 /g, 0.030 cc/g, and 49.020 Å, respectively.…”

n-Hexane Isomerization Over Nickel-Containing Mordenite Zeolite

“…The analysis of X-ray diffraction patterns for synthesized samples (Fig. 3) shows that all catalysts have a crystalline structure corresponding to the structure of MOR zeolite (JCPDS Card # 29-1257) [24]. XRD Three characteristic peaks for nickel (2q = 44.5°, 51.8°, and 76.4°), corresponding to Miller indices (111), (200), and (222), are also shown in Fig.…”

“…Isotherms are typical ones for micro/mesoporous sorbents, which are characterized by a steep rise at low P/P s values assigned to the formation of equilibrium Langmuir adsorbate monolayers and a hysteresis loops over higher P/P s values [21][22][23][24]. Isotherms belong to IVa type with H3 hysteresis loop according to the classification of IUPAC [21], and this could be related to cylindrical pore channels.…”
