Adsorption of the Orange Methyl Dye and Lead (II) by the Cationic Resin Amberliteand#174;IRC-50: Kinetic Study and Modeling of Experimental Data

Abstract

During this present study, we tested the adsorption performance of heavy metal ions; bivalent lead (Pb (II)) and the anionic dye (methyl orange (MO)) from model aqueous solutions with the ion exchange resin of the Amberliteand#174;IRC-50 type. This performance was evaluated using inductively coupled plasma (ICP) and atomic absorption spectroscopy (AAS). The pH of the solution was adjusted to 6.5 for the bath temperature, the initial mass concentration of Pb (II) and MO was adopted at 20 mg/L, the mass of the resin-type adsorbent Amberliteand#174;IRC-50 was taken at 0.1g and the adsorption capacity Qe was studied. The results obtained during this study show that the kinetic study of the adsorption was obtained at the contact time t = 30 min for the metal Pb (II) and at t = 60 min for the dye MO. These results also showed that the equilibrium of adsorption was reached at time t = 60 min with an adsorption performance of around 99% for Pb (II) and around 96% for MO. Note that the parameters of different mathematical models indicate that the adsorption process is spontaneous in the second degree.

Adsorption of Methylene Blue Dye and Analysis of Two Clays: A Study of Kinetics, Thermodynamics, and Modeling with DFT, MD, and MC Simulations

“…Thus, at higher pH values, A negative charge exists at the surface, while the surface is positively charged at pH levels between 7.97 and 8.98. The increased adsorption of methylene blue (MB) in basic media is thus explained by the electrostatic attraction between the surface of the negatively charged adsorbent and the positively charged MB molecules. − …”

Physicochemical Characterization of Clay and Study of Cationic Methylene Blue Dye Adsorption

“…A band at 1004.99 788.00 and 696.00 cm –1 , was assigned to elongation vibrations of Si–O . Two different bands at 867.29 and 713.25 cm –1 , indicate respectively the presence of Si–O–Al and Ca–CO . A band 794.14 cm –1 corresponds to quartz, there is the bands characteristic of constitutive water that show up about 3000.00 cm –1, and two vibrational bands around 3624.61 and 3446.47 cm –1 corresponding to the Al–OH-Al elongation …”

Study of the mechanical behavior of swelling and highly compacted clays in road construction

“…3 Description of the swelling phenomenon Analysis of previous work shows that there are two types of swelling, intra-particle (inter-foliar) swelling and (inter-particle) swelling Figure 1, according to mouroux [22].…”

“…Other parameters independent of the structure of the clays and the chemical composition of the moisturizing solution can have an important in uence on the swelling, we cite in particular [22]. The different soil samples studied in this article designated by the names of the localities from which they were taken.…”

“…The proposed work falls within this perspective, it consists in studying the mechanical behavior of a natural clay of the Kenitra region for possible use in road construction. It can be a valuable contribution to the solution of swelling clays presenting a clean, even economical alternative, knowing that available quantities treat swollen clays [22]. Claimed in relation to the development of the country and the large number of projects launched under construction.…”
