“…Marin et al removed AB 113 from aqueous solutions by batch technique onto Amberlite IRA 402 (Cl − ). For this, 0.5 g of dried IRA 402 (Cl − ) was stirred for 90 min with 50 mL of 2.07 g/L AB 113, where the Qe was 117 mg/g [ 28 ]. Moreover, several publications reported AB 113 adsorption using low-cost adsorbents.…”

“…The percentage of AB 113 in liquid phases increased in acidic solutions with increase of HCl concentration. The AB 113 remained in IRA 402 mass up to 2 M HCl solutions [ 28 ]. Furthermore, in another study, Marin et al reported acidic influence by Amberlite IRA 400 (IRA 400) resin loaded with Acid Orange 10 (AOG 10).…”

“…The following hypothesis for the metal ions recovery from MS-AB and 113 XAD7HP–AB 113 can be taken into consideration: (i) by the influence of the regeneration agent the metallic ion (M X+ ) is released into solution in the form of AB 113-M X+ if the AB 113 with M X+ forms a stabile complex; or (ii) under the action of the regeneration agent are released in solution only M X+ and AB 113 still remaining loaded in the mass of material [ 28 ]. In this, the aim was to recover only metal ions.…”

This research had two stages of development: during the first stage, the purpose of the research was to evaluate the adsorption properties of the natural polymer represented by shredded maize stalk (MS) and by Amberlite XAD7HP (XAD7HP) acrylic resin for removal of toxic diazo Acid Blue 113 (AB 113) dye from aqueous solutions. The AB 113 concentration was evaluated spectrometrically at 565 nm. In the second stage, the stability of MS loaded with AB 113 (MS-AB 113) and of XAD7HP loaded with AB 113 (XAD7HP-AB 113) in acidic medium suggests that impregnated materials can be used for selective removal of metal ions (Cr3+, Zn2+ and Mn2+). The metal ions using atomic absorption spectroscopy method (AAS) were determined. The use of MS-AB 113 ensures a high selectivity of divalent ions while the XAD7HP-AB 113 had excellent affinity for Cr3+ in the presence of Zn2+ and Mn2+. As a consequence, two advanced polymers, i.e., MS-AB 113 and XAD7HP-AB 113 that provide huge capacity for removal of Zn2+, Mn2+ and Cr3+ from acid polluted wastewater were obtained.

“…The performance of the adsorption process was evaluated based on the adsorption capacity Q t (mg/g) which represents the mass of M X+ retained by one gram of MS at a time, t [ 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ]:

where C i and C t (mg/L) represent the concentrations of the supernatant before and after at time t of the adsorption process, V (L) the volume of samples to be tested, m (g) is the mass of the MS.…”

In this research, eco-friendly material represented by maize stalk (MS) obtained after acid treatment was employed for simultaneous removal of Cu2+, Pb2+, Ni2+, Cd2+, Cr3+ and Fe3+ (MX+) from simulated textile aqueous matrix and tannery wastewater produced by the leather industry. The acid treatment of MS was done with 4 M HCl. The influence of experimental parameters was evaluated in order to optimize the adsorption process for simulated textile matrix. The contact time 10–60 min and initial concentration of 0.5–1 mg/L MX+ influence were studied by batch method. Additionally, the adsorption data of MX+ onto MS was fitting by kinetic and isotherm models. The results obtained showed that the 60 min was necessary to reach adsorption equilibrium of the MS. The adsorption capacity of MS was 0.052 mg Cu2+/g of MS, 0.024 mg Pb2+/g of MS, 0.042 mg Ni2+/g of MS, 0.050 mg Cd2+/g of MS, 0.056 mg Fe3+/g of MS and 0.063 mg Cr3+/g of MS at pH = 4.2. The Langmuir model described the adsorption process very well. The MS showed huge selectivity for Cr3+ and Fe3+ in the presence of Cu2+, Pb2+, Ni2+ and Cd2+. The adsorption of MX+ from liquid phases were analyzed by spectrometric adsorption method (AAS). The solid phases of MS before and after adsorption by TG and SEM analysis were characterized. When MS was used for removal of MX+ from tannery wastewater, two major issues were investigated: First, the decrease of MX+ content from highly polluted and difficult to treat tannery wastewaters by improve its quality and in the second part, specific recovery of MX+ from MS mass increasing the economic efficiency of metals production based on green technology.

Macro-Reticular Ion Exchange Resins for Recovery of Direct Dyes from Spent Dyeing and Soaping Liquors

et al. 2022

Dyes are a major class of organic pollutants that are well-known for their harmful impact on aquatic life and humans. Several new strategies for removing colours from industrial and residential effluents have recently emerged, with adsorption being the best option. The current study looked at the recovery of direct dyes from aqueous streams for reuse using macro-reticular ion exchange resins (IERs). The investigation includes dyeing single jersey cotton grey textiles with direct dyes from the Isma dye Company in Kafr El Dawar, Egypt. After centrifuging and separating the supernatant liquid, solutions from thirteen different dyes, produced at an average concentration between the wasted and soaping liquor concentrations, were calculated spectrophotometrically from the first dyeing trials. Kinetic data were well fitted with pseudo-second-order rate kinetics. The amounts of dye retained by the anion exchangers increased with a rise in temperature in the case of Strong Base Resin (SBR) and vice versa for Weak Base Resin (WBR). Batch adsorption experiments with SBR and WBR were conducted for each dye, and both Freundlich and Langmuir isotherms were constructed. It was found that adsorption obeyed both isotherms, that monolayer adsorption took place, and that the dye molecular weight, structure, and solubility, as well as the type of anionic resin used, had varying effects on the extent of absorption. The monolayer sorption capacities Q0 determined from the Langmuir isotherm model for the strongly and weakly basic anion exchangers were found to be 537.6 and 692 mg/g for Direct Yellow RL, respectively. As a result, Yellow RL exhibited the greatest adsorption on both SBR and WBR. Orange GRLL, Blue 3B, and Congo Red, on the other hand, were the poorest colours absorbed by the IERs, whereas Blue RL demonstrated good adsorption by SBR and accelerated adsorption by WBR. Most of the dyes may be recovered and reused in this manner.
