“…Many studies have examined non-conventional alternative sorbents produced from renewable and low-cost resources in terms of their effectiveness compared to the traditional synthetic ion exchangers (Hasany and Ahmad, 2006;Shaheen et al, 2012bBadruddoza et al, 2013). One of such alternative sorbents is CFA, which has received special attention as an economical sorbent for removing trace elements from wastewater due to its abundance and easy availability.…”

“…Consequently, composite or hybrid structures are promising materials for water treatment. The widely used host materials for nanocomposite include carbonaceous materials like granular activated carbon [25], silica [26][27][28][29], cellulose [30,31], chitosan [32,33], sand [34,35], and polymers [36][37][38]. Some examples include the immobilization of metal oxides on carbon nanotubes for lead, arsenic, and fluoride removal 2 Journal of Nanomaterials [39][40][41], activated carbon immobilized on carbon nanotubes for chromium removal [25], and carbohydrate and iron oxide on multiwalled carbon nanotubes for zinc removal [42].…”

Frustules or the rigid amorphous silica cell wall of unicellular, photosynthetic microalgae with unique porous architecture has been used to synthesize a composite by immobilizing zirconium and iron oxides on its surface and in the pores. This was effective for removal of Se from water, which is an emerging contaminant that is a micronutrient at low concentrations but toxic at high concentrations. The adsorption isotherms followed both Langmuir and Freundlich models, and the composite was regenerable. The Langmuir maximum adsorption capacity for Se(IV) ( ) was 227 mg/g, which is among the highest ever reported. The research findings highlight the synthesis of bimetallic composite as well as the potential of diatoms as hosts for nanomaterials for use in water treatment.

Alginate has been extensively used as absorbents due to its excellent properties. However, the practical application of pure alginate has been restricted since the saturated adsorbent has weak physical structure and could not be regenerated easily. In this study, a lowcost and renewable composite MnO 2 @alginate/Mn adsorbent has been prepared facilely for the absorptive removal of antibiotic wastewater. FE-SEM, FTIR, and XRD analyses were used to characterize the samples. The norfloxacin (NOR) was used as an index of antibiotics. More specifically, the batch absorption efficiency of the adsorbents was evaluated by pH, contact time with different NOR concentration, and the temperature. Thus, the performance of absorption kinetic dynamics and isotherm equations were estimated for the adsorptive removal process. Parameters including Δ 0 , Δ 0 , and Δ 0 were utilized to describe the feasible adsorption process. To regenerate the saturated absorptive sites of the adsorbent, the heterogeneous Fenton-like reactions were trigged by introduction of H 2 O 2 . The results showed that the in situ regenerating has exhibited an excellent recycling stability. The high activity and the simple fabrication of the adsorbents make them attractive for the treatment of wastewater containing refractory organic compound and also provide fundamental basis and technology for further practical application.
