Adsorption equilibrium and thermodynamics of anionic reactive dyes from aqueous solutions by using a new modified silica gel with 2,2′-(pentane-1,5-diylbis(oxy))dibenzaldehyde
Abstract
Abstract The 2,2′-(pentane-1,5-diylbis(oxy))dibenzaldehyde (BP) functionalized silica gel (Si-APTES-BP) was synthesized successfully by a normal method and a inverse method. These new materials were characterized by Fourier Transform Infrared (FT-IR), Scanning Electron Microscopy (SEM), Thermogravimetric Analyzes (TGA) and Ultraviolet Visible (UV–vis). The modified silica gel with normal method was used as a sorbent for removal of anionic reactive dyes Reactive Blue 19 (RB19) and Reactive Yellow 84 (RY84) from their aqueous solutions by batch adsorption procedure. The batch adsorption experiments were performed to study the effect of various experimental parameters such as the solution pH, contact time, initial dye concentration, adsorbent dose and temperature. The results showed that the adsorption capacity of RB19 and RY84 dyes were enhanced with increase temperature of solution. The maximum uptake value for RB19 and RY84 dyes were obtained at pH 5 and pH 8, respectively. The isotherm data of both investigated dyes were analyzed by the Langmuir and Freundlich adsorption models. Based on the correlation coefficient values, it has been deduced that the Langmuir model is better fitted to the experimental data. The Langmuir maximum adsorption capacity of the Si-APTES-BP at 298 K was found to be 37.45 for RB19 and 32.36 mg/g for RY84, respectively. In addition, thermodynamic studies were conducted to calculate the changes in Gibbs free energy (ΔG°), enthalpy (ΔH°) and entropy (ΔS°). The negative values of ΔG° and the positive value of ΔH° indicated that the adsorption process of both investigated dyes was a spontaneous and endothermic process in nature. The reusability of Si-APTES-BP has proven that the adsorbent is durable and cost-effective. Therefore, the silica gel modified with 2,2′-(pentane-1,5-diylbis(oxy))dibenzaldehyde can be used as an effective adsorbent for the removal of anionic reactive dyes from aqueous solutions.

“Silicon based materials have been studied extensively for pollutants adsorption as well 51, 52 . Their interesting properties such as ability for a wide range of pore size and surface areas, durability, ease of functionalisation and relatively cheaper regeneration compared to activated carbon, have made them excellent candidates for water treatment with many examples on dye adsorption 53-56 .”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
