“…In another study, Jiang et al worked on assembly of polyaniline nanofibers on calcium alginate beads by competitive adsorption-restricted polymerization approach [7]. One more magnetic adsorbent (called magsorbent) was developed by Bée et al by encapsulation of magnetic functionalized nanoparticles in calcium-alginate beads [8]. It is well known that synthesis of nanoparticles is capital intensive process and requires a great care at each stage of operation.…”

A B S T R A C TThe work is based on augmentation of active sites of calcium alginate bead by immobilizing bromelain to remove lead(II) from simulated solution. The optimum immobilization condition as specified by response surface methodology is as follows: initial concentration of sodium alginate, bromelain, and calcium chloride are 20, 21.09, and 20 g/L, respectively, at pH 7 and 35˚C and the sample, thus prepared, is termed as alginate immobilized bromelain (AIB). Maximum 99.5% lead(II) has been removed when 30 mL lead(II) solution having initial concentration of 0.0048 mmol L −1 has been treated with 5 g of AIB at pH 7 and 35˚C. 77.9% lead(II) has been recovered when 1 g of spent adsorbent is stirred in 100 mL of solution having pH 2 for 30 min. The removal of lead(II) using AIB and, thereby, simultaneous inhibition of enzyme have been modeled both statistically and empirically.

“…Indeed, the use of magnetic adsorbents (called here magsorbents) is a promising way due to their easy and fast removal from water through the application of an external field [10][11][12]. Several efficient magnetic adsorbents have been reported in the literature but most of them are especially effective in the removal of cationic or anionic pollutants [13][14][15][16][17][18]. The difficulty increases for removing of weakly ionisable or non-ionic organic pollutants.…”

The paper focuses on the removal of p-nitrophenol by an adsorption process. A magnetic adsorbent was synthesized by encapsulation of magnetic functionalized nanoparticles using alginate as a green biopolymer matrix. A cationic surfactant, cetylpyridinium chloride (CPyCl), was used to confer a hydrophobic character to the magnetic beads and thus to promote their adsorption efficiency. The effect of different parameters such as initial concentrations of both PNP and CPyCl, contact time and solution pH value on the adsorption of PNP in the presence of CPyCl was investigated. It should be noted that combination of magnetic and adsorption properties in a same material is an interesting challenge which could overcome the recovery problems of pollutant-loaded adsorbent. min whereas 90% adsorption was attained within 2 hours. It should be noted that combination of magnetic and adsorption properties in a same material is an interesting challenge which could overcome the recovery problems of pollutant-loaded adsorbent.
