Novel hyper-cross-linked polystyrene/polyacryldiethylenetriamine (HCP/PADETA) interpenetrating polymer networks (IPNs) were prepared, characterized and evaluated for their adsorption and separation properties using hyper-cross-linked polystyrene (HCP) as the reference. In spite of its much lower Brunauer-Emmett-Teller surface area and less pore volume, HCP/PADETA IPNs possessed a preferable pore structure and appropriate polarity, resulting in a larger equilibrium capacity, faster adsorption rate, higher dynamic breakthrough and saturated capacity towards salicylic acid than HCP. In particular, HCP/ PADETA IPNs had a higher enrichment factor for salicylic acid over phenol, leading to the high-efficiency separation of salicylic acid from phenol in their mixed solution.

“…At present, researchers have tried a number of methods to remove RhB dye from aqueous solution, such as adsorption [6,7], the electro-Fenton process [8], photodegradation [9], sonochemical degradation [10] and membrane separation [11]. Among them, adsorption has been regarded as one of the most potential methods and widely favored by researchers because of its advantages such as convenient operating conditions, good treatment effects and an abundant source of raw materials.…”

Rhodamine B (RhB) is a synthetic organic dye widely used in textile, paper-making, leather manufacture, stained glasswork, the cosmetics industry and many other industries due to its high tinting strength, bright color and high stability [1, 2]. These industries produce a great amount of RhB dye wastewater, with the characteristics of high colority, poor biodegradability and heavy toxicity [3]. The traditional biological method hardly meets the emission requirements, while directly draining into water would cause serious threats to the environment and human health. Previous experimental studies have

“…Rh-B has been reported to irritate the skin, eyes, respiratory tracts, induce hormonal disturbances in addition to being neurotoxic and genotoxic. Also, it readily undergoes anaerobic degradation in water producing carcinogenic amines from reductive amination and remediation using conventional and biological methods has not yielded great results due to its complex structure, toxicity and high molecular weight [5][6][7][8][9][10][11][12].…”

“…Adsorption provides one of the best ways of dye removal and as such has been applied for Rh-B uptake with different adsorbents such silver nanoparticle from cobweb [3], activated carbon [4], ferrocene-functionalized carbon nanotubes [5], acid and alkaline-functionalized Musa paradisiaca biochar [6], nanocomposite hydrogel [7], animal bone meal [8], exhausted coffee ground [9], gelatin/activated carbon composite beads [10], Fe/ZnO-shell shrimp nanocomposite [11], polar-functionalized post-cross-linked resins [12], calcined egg shell [13], seeds of Aleurites moluccana [14], zinc oxide loaded activated carbon [15] and anodic porous alumina in sodium dodecyl sulphate solution [16] amongst other methods. Although, excellent adsorptions of Rh-B have been achieved with these adsorbents, drawbacks from their applications relating to limited abundance, low adsorption capacity, lack of reproducibility, renewability, biodegradability in addition to expensiveness and probable secondary pollution which could create distress in the environment required the use of biodegradable bio-composite which are abundantly available.…”

Adsorption Behaviour of Rhodamine B on Hen Feather and Corn Starch Functionalized with Green Synthesized Silver Nanoparticles (AgNPs) Mediated with Cocoa Pods Extracts

This study reports useful application of biodegradable polymeric materials functionalized with silver nanoparticle (AgNPs) biosynthesized from cocoa pods as effective adsorbent for dye wastewater purification. Corn starch and hen feather were functionalized with AgNPs for adsorption of rhodamine B (Rh-B). All adsorbents were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy and X-ray diffraction. Decreased intensities of peaks, superior rougher cavities and smaller grain diameter of functionalized biomaterials affirmed the functionalization. Effects of pH, contact time, initial Rh-B concentrations and temperature were investigated and found to be significantly important. Four isotherm models were used to describe the adsorption process with Freundlich being the most suitable for all adsorbents indicating Rh-B adsorbed on heterogeneous multilayer surfaces of adsorbents. AgNPs modification greatly enhanced maximum monolayer adsorption capacities (q max) of feather (4.27-56.53 mg g −1) and starch (1.176-48.60 mg g −1) by 30-and 40-fold respectively. Kinetic rates of adsorption for starch best fitted Elovich, pseudo first order for feather whereas pseudo second order best suitable for starch-AgNPs and feather-AgNPs. Energies (3.89-7.68 kJ mol −1) of adsorption suggest that adsorption of Rh-B onto the adsorbents was by physiosorption. The negative values of ∆H° and ∆G° imply that adsorption processes were exothermic and spontaneous. Results in this study show that surface functionalization of starch and feather improved their adsorptive performances and will find valuable applications in dye remediation due to their biodegradability and cost-effectiveness.
