“…It is necessary to further improve the extraction selectivity of CuFe 2 O 4 for separation of targets. In the same paper, the extraction or adsorption of rhenium ions with amines is a common method; the functional group of amine had a high affinity for rhenium ions [23,24].…”

“…The similar chemical behaviors and properties of rhenium and molybdenum make the separation quite difficult [1]. Various techniques such as solvent extraction [2,3], ion exchange [4,5], chemical precipitation [6], and adsorption [7,8] have been used extensively for the recovery of rhenium and molybdenum. Moreover, adsorption techniques have gained favor recently due to their efficiency in the removal [9,10].…”

An effective method based on magnetic solidphase extraction for the selective recovery of rhenium and molybdenum has been developed using diethylaminefunctionalized magnetic CuFe 2 O 4 (NH 2 @CuFe 2 O 4 ) as adsorbents. Various experimental parameters that could affect the extraction efficiency had been investigated in detail. NH 2 @CuFe 2 O 4 exhibited high adsorption ability and selectivity to ReO À 4 and MoO 2À 4 ; selective separation of ReO À 4 and MoO 2À 4 could be achieved by adjusting pH of the aqueous solution. The ReO À 4 =MoO 2À 4 adsorption reaction was found to be fast, and the adsorption equilibrium was attained within 6.0 min following a pseudo-secondorder model with an observed rate constant (k 2 ) of 0.0215 mgÁg -1 Ámin -1 /0.0496 mgÁg -1 Ámin -1 at 298 K. The adsorption data could be well interpreted by the Langmuir model. The maximum adsorption capacities for ReO À 4 and MoO 2À 4 obtained from the Langmuir model are 41.667 and 62.893 mg g -1 , respectively. The extraction recovery of ReO À 4 =MoO 2À 4 was more than 93 % from Mo-Re simulated industrial leach liquor.

“…Algal biomasses have been employed in recent years to remove heavy metals cations such as Cu 2+ , Zn 2+ and Cd 2+ , showing good performance to remediate effluents polluted with heavy metals cations. Toxic oxoanions such as CrO 4 2− , MoO 4 2− and ReO 4 − were also effectively removed from polluted effluents employing diverse algal biomasses …”

BACKGROUND In recent years, the discharge of heavy metal ions in natural waters has become a serious problem. Among the various techniques that have been employed for heavy metal removal, adsorption is highly effective and economical because low‐cost adsorbents can be employed. Brown algae are a potential biosorbent because of their high uptake capacities for various heavy metal ions. Petalonia fascia biomass immobilized in an agar matrix was tested as a new removal agent of MoVI from contaminated waters. RESULTS Sorption studies were performed in batch and continuous systems. Petalonia fascia has a high adsorption capacity (1376 ± 2 mg g−1) at 20 °C and pH 1.0. Participation of hydroxyl and carboxylate functional groups in the adsorption of molybdate anions was confirmed by FT‐IR analysis. SEM images showed that morphological surface changes happen after MoVI sorption. Mean free energies of sorption and activation parameters demonstrate that the sorption mechanism was chemical sorption. MoVI sorption onto brown seaweed surface was spontaneous and exothermic. Petalonia fascia has an energetically heterogeneous surface. Continuous sorption data were best fitted by a modified dose–response model. Scale‐up of the sorption processes was achieved applying a bed depth service time (BDST) model. The critical bed depth, Z0 was 1.7 cm. CONCLUSIONS Petalonia fascia biomass is a good adsorbent material for MoVI and it can be used in fixed bed columns for the purification of MoVI contaminated effluents. The high value of qmax and the low cost of this seaweed make this biomass a good sorbent for use in continuous treatment of groundwater and effluents contaminated with molybdate anions. © 2016 Society of Chemical Industry

“…Various treatment techniques such as precipitation (Ku and Jung 2001), electrochemical (Cooper et al 2007), ion-exchange (Dąbrowski et al 2004), coagulation/electrocoagulation El-Samrani et al 2008), and electrodialysis (Sadrzadeh et al 2008) are rather inept and/or cost prohibitive. Biosorption, using sustainable resources, is considered a promising process due to its high removal efficiency, low cost, mild operating conditions and good performance in the removal and recovery of heavy metal ions/dyes from dilute aqueous solution (Khan et al , 2014Lou et al 2015). Among various wastes biomass for metal removal such as yeast (Göksungur et al 2005;Han et al 2006), bacteria (Halttunen et al 2007;Loaic et al 1997;Teemu et al 2008) and fungi (Kapoor et al 1999), algal biomass is favorite adsorbent because of its low cost and widespread abundance (Carlsson et al 2003;He and Chen 2014).…”

In this study, the adsorption efficiency of epichlorohydrin modified fresh water green algal biomass was assessed for Pb(II) and Cd(II) uptake from aqueous solution. The process parameters such as contact time, dose, initial metal concentration, solution pH and temperature were optimized. The Langmuir, Freundlich, Temkin and Dubnin-Redushkevich isotherm model was applied to the equilibrium data, which best fitted the Langmuir isotherm indicating homogenous distribution of adsorption sites. The monolayer adsorption capacity was 100.00 for Pb (II) and 72.46 mg/g for Cd(II) adsorption. The kinetic data was best described by pseudo-second order model, with intraparticle and liquid film diffusion controlled mechanism. The negative values of Gibbs free energy change (ΔG º ) and positive enthalpy change (ΔH º ) showed that adsorption process was spontaneous and endothermic. The functional groups, surface morphology and elemental composition of adsorbent, before and after adsorption, was evaluated using FTIR spectra, SEM and EDS studies. The study revealed that the modified algal biomass can effectively and efficiently remove the title metal ions from aqueous solution.
