The present work describes the synthesis of hydroxyapatite-lambda carrageenan CaHAp-(k-Carr) using an aqueous coprecipitation method. The characterization of the prepared hybrid compounds was achieved using chemical analysis, Fourier Transform Infrared spectroscopy, powder X-ray diffraction, scanning electron microscopy, and specific surface area. The results gleaned from X-ray powder analysis proved the presence of (k-Carr) and revealed that the increase of its concentration leads to the decrease of the CaHAp crystallinity. Fourier transform Infrared spectra show the presence of (k-Carr) and CaHAp characteristic vibrations in the resulting product. Scanning electron microscopy analyses reveal that the morphology of particles was changed by grafting and they are characterized by aggregates of different sizes and irregular shapes. After grafting BET measurements yielded particle specific surface areas ranging from 93 to 260 m 2 g 21 depending on the grafted biopolymer. The prepared products were, further, applied for the adsorption of methylene blue (a cationic dye) from aqueous suspension. The adsorption capacity was determined with respect to pH value, the initial dye concentration, time contact, and temperature. The kinetic, thermodynamic, and adsorption isotherm models were assessed for the description of the dye adsorption process. The experimental resulting data show that the prepared hybrid compound CaHAp-(k-Carr) is an efficient adsorbent for the removal of dyes.

“…Recently, we demonstrated that 4-methyl-2-(naphthalen-2-yl)-N-propylpentanamide functionalized ethoxy-silica could be used as an efficient adsorbent to remove a wide range of dyes (acid, direct, reactive and basic) from an aqueous suspension 11 . In particular, the most frequent examples given were forest products that were proven to be competent and were used as adsorbents are palm ash 12 , rice husk 13 , sawdust and almond Shell 14 , 15 .…”

For the first time, co-polymer of dimethyl diallyl ammonium chloride and diallylamin (PDDACD) was used to modify the films derived from the waste of palm date fruits, which were then investigated by the purification of colored aqueous solutions. The physico-chemical characteristics were identified using data color, FT-IR spectroscopy, and SEM features. The modified films were evaluated as adsorbents of Methylene Blue (MB), Direct Yellow 50 (DY50), Reactive Blue 198 (RB198) and Naphtol Blue Black (NBB). High retention capacities were achieved in the following order: The equilibrium da DY50 (14 mg g−1) < RB198 (16 mg g−1) < NBB (63.9 mg g−1) < MB (150 mg g−1). The kinetic modeling of the data revealed that the adsorption data follows the pseudo second order model. It was fitted to the Langmuir, Freundlich, Temkin, and Dubinin-Redushkevich equations, and the data best fit the Freundlich model indicating that the adsorption might occur in the heterogeneous adsorption sites. These results reveal that PDDACD modified films are valuable materials for the treatment of industrial wastewater. Moreover, the as-prepared adsorbent is economically viable and easily controllable for pollutant adsorption.

“…According to the plots and R 2 values (Figure 2), the adsorption of CR onto all studied jute fabrics undoubtedly followed the pseudo-second-order model (R 2 ⩾ 0.995) indicating that the chemisorption process is primarily represented. 19 Panda et al 20 reported that in batch experiments under rapid stirring conditions, transportation of CR from the solution phase into the adsorbent pores may also be considered a rate-controlling stage. In the current study, fabrics oxidized with 0.4% NaIO 4 have higher adsorption rates than those oxidized with 0.2% NaIO 4 , which is clearly seen from their lower pseudo-second constant values (k 2 , Table 2).…”

The raw jute fabric was oxidized with 0.2% or 0.4% NaIO4 for 60 or 120 min to obtain valuable adsorbents for the textile dye Congo Red (CR). Batch adsorption experiments were carried out as a function of solution pH, contact time, initial CR concentration, and temperature. At an initial CR concentration of 25 mg/L, the raw jute possessed the lowest adsorption due to the lowest availability and content of carboxyl and aldehyde groups capable of binding dye. The fabrics oxidized for 60 min with 0.2% NaIO4 and 120 min with 0.4% NaIO4 reached equilibrium adsorption after 240 and 330 min, respectively. The adsorption of CR onto studied fabrics followed the pseudo-second-order model indicating that the chemisorption process is primarily represented. Within the studied range of CR concentrations (25–100 mg/L), its adsorption onto fabric oxidized for 120 min with 0.4% NaIO4 obeys the Langmuir isotherm model (i.e. adsorption occurs at specific, energetically equivalent adsorbent sites with monolayer coverage of CR over a homogeneous surface), wherein the calculated maximal adsorption capacity is 12.863 mg/g. A thermodynamic study revealed the spontaneous and endothermic character of CR adsorption onto jute fabric. Based on the recorded ATR-FTIR spectra before and after CR adsorption, it is suggested that repulsion, hydrogen bonds, and π-π stacking interactions are involved in the binding of CR onto jute fabrics.
