“…The solubility of micelles will increase at higher temperatures resulting in an enhanced removal process of CR and MO dyes. This has been shown in studies conducted by Hamed et al in 2018 and 2016 68,69 , as well as by Hamed and Aglan in 2019 65 . The thermodynamic functions, such as Gibbs-free-energy (ΔG°), enthalpy (ΔH°), and entropy (ΔS°), for the solubilization procedure of this extractive removal, were calculated using the methodology described by Melo…”

Cloud point extraction (CPE) was used in this work to eliminate anionic dyes, Cresol red and Methyl orange, in the form of binary combinations. To remove these dyes from aqueous solutions, Triton X-100 was utilized. We chose wavelengths of 365 nm and 520 nm for Cresol red and Methyl orange, respectively, using a derivative spectrophotometer and first-order derivatives. The response surface methodology was then utilized to ascertaint he effect of surfactant concentration, temperature, and time on the dyes' elimination processes. The quadratic mathematical model obtained from the Box-Behnken design (BBD) matrix was used and developed to estimate the influence of each variable and its relationship with the elimination parameters. Using model equations and comparison between predicted and empirical values, coefficients of determination (R2) bigger than 0.97 were obtained. By applying variance analysis, significance and anticipation of models were validated, and process variables were estimated. The data demonstrate that the mentioned dyes adsorption may be described using the model of pseudo-first-order in kinetic modelling. The data illustrates that the analyzed dyes adhere to the Langmuir model, with a correlation value of 0.86 for Cresol red and 0.87 for Methyl orange. The monolayer capacity (Qmax) was determined to be 0.77 mol/mol for Cresol red and 26.41 mol/mol for Methyl orange.

“…The results revealed that the low-cost prepared carbonaceous sorbents exhibited good sorption capacities compared with other materials as reported in the literatures. The results also indicated that the prepared sorbents can be considered as a promising sorbents for the removal and recovery of different radionuclides species, even compared to some other low cost sorbents and activated carbons previously suggested for the uptake of different radionuclides from aqueous solutions [48][49][50].…”

Delonix regia pods have been used to produce high-efficiency and low-cost activated carbons using different activation methods. The ability of these prepared sorbents to remove cations [ 137 Cs, 85 Sr, La(III), Eu(III), Co(II), U(VI)] and anions [ 75 Se, Cr(VI), Mo(VI)] was evaluated in mono-component systems and the sorbents number 11, 13, 25, and 35 showed high removal efficiency. These sorbents also show the high ability to remove organic pollutants such as methylene blue and phenol. This study highlighted the extensive applicability of these low-cost sorbents in the sequestration of anionic and cationic radionuclides from real radioactive wastewaters and different environmental samples.

With the aim to find new efficient extractants for recovery of f-block elements from processing wastes of different origin, we have compared a series of phosphoryl-containing podands, including (2-(diphenylphosphorylmethoxy)phenyl)diphenylphosphine oxide 1 and its analogues 5–7, where the ArP(O)Ph2 group of phosphine oxide type is replaced by phosphonic fragments. Quantum-chemical modelling of the structures of phosphoryl-containing podands 1 and 5–7 has been performed, which was later confirmed by the data of X-ray diffraction. The features of extraction of nitric acid, as well as U(VI), Th(IV), Nd(III), and Ho(III) with compounds 1 and 5–7 from nitric acid media into 1,2-dichloroethane have been studied. The compositions of extracted complexes have been determined.
