“…The solution pH is a critical variable in the adsorption system. The solution pH can influence the charge of the adsorbent surfaces, ionization degree, and adsorbent speciation [ 4 ]. Figure 8 a clearly shows that the pH of the solution had a considerable impact on the Pb(II) adsorption efficiency.…”

“…For example, adsorption, absorption, membrane treatment, and cryogenic distillation have been used for CO 2 capture [ 5 ]. Precipitation, solvent extraction [ 3 ], ultrafiltration [ 4 ], and adsorption were employed to remove heavy metals. Among these methods, adsorption is one of the best choices and has proven to be inexpensive and practical, owing to its easy and cheap process.…”

Studying the effect of functional groups on the porosity structure and adsorption efficiency of polymer materials is becoming increasingly interesting. In this work, a novel porous polyaminal-linked polymer, based on naphthalene and melamine (PAN-NA) building blocks, was successfully synthesized by a one-pot polycondensation method, and used as an adsorbent for both CO2 and heavy metals. Fourier transform infrared spectroscopy, solid-state 13 C NMR, powder X-ray diffraction, and thermogravimetry were used to characterize the prepared polymer. The porous material structure was established by field-emission scanning electron microscope and N2 adsorption–desorption methods at 77 K. The polymer exhibited excellent uptake of CO2, 133 mg/g at 273 K and 1 bar. In addition, the adsorption behavior of PAN-NA for different metal cations, including Pb(II), Cr(III), Cu(II), Cd(II), Ni(II), and Ba(II), was investigated; a significant adsorption selectivity toward the Pb(II) cation was detected. The influence of pH, adsorbent dose, initial concentrations, and contact time was also assessed. Our results prove that the introduction of naphthalene in the polymer network improves the porosity and, thus, CO2 adsorption, as well as the adsorption of heavy metals.

“…The rapid growth of industries such as tanneries, batteries, metal plating facilities etc. is the main reason for water contamination by a high amount of toxic heavy metal ions such as nickel, copper, mercury and cadmium . Extensive use of nickel in the above industries has generated wastewater containing Ni 2+ ions in an aquatic environment with concentrations higher than the limitations prescribed by the World Health Organization .…”

In this study, a porous organic triazine-based polyimide (PPI network) was prepared from 2,4,6-tris(hydrazino)-s-triazine and 3,4,9,10-perylenetetracarboxylic dianhydride. TGA, Fourier transform infrared spectroscopy, field emission SEM, XRD and a nitrogen sorption study confirmed the PPI network structure. Then, the synthesized PPI network was used to evaluate Ni 2+ ion removal from aqueous solution and the effective parameters on adsorption functions of Ni 2+ ions such as initial concentration, contact time and pH of the solution in batch adsorption experiments was studied. The results showed that the maximum adsorption capacity (q m ) of Ni 2+ ions was 36.1 mg g −1 in only 30 min with a pH of 7. The kinetics and adsorption isotherm were identified to be better fitted by the pseudo-second-order model and the Langmuir model, respectively. Based on the results, the proposed adsorbent has good potential for removing Ni 2+ ions from aqueous solutions.

“…To date, a great variety of materials have been reported for the timeconsuming organic pollutant removal processes from industrial effluents. The most important materials include functionalized mesoporous silica, 9 activated carbons, 10 ordered mesoporous carbons, 11 metal-organic frameworks (MOFs), 2,[12][13][14] porous organic polymers (POPs), [15][16][17] clays, 18,19 and zeolites. 20,21 A quick look at the reported materials proves that the ideal adsorbents should have high chemical and thermal stability, good selectivity, costefficiency, easy preparation and regeneration process, fast adsorption kinetics, and high adsorption capacity.…”

Water pollution is becoming an up-rising threat to the environment and human being in recent years and turning to a major global challenge. The wastewaters released by the textile and dyestuff industries are one of the major sources of contamination. The aim of this work is preparation of stable, reusable, and fast adsorbent for complete removal of both cationic and anionic pollutants from industrial wastewaters. To obtain these goals, an amine-sulfone-rich mesoporous organic polymer (Daps-POP) was synthesized, structurally characterized and applied for removing of methylene blue (MB) and direct blue 108 (DB-108) as cationic and anionic model dye pollutants, respectively.The affecting variables on the adsorption process were optimized and the possible adsorbate-adsorbent interactions were identified. The synthesized Daps-POP was applied to industrial wastewaters and presents complete removal of model dye pollutants proving the idea of using POPs in industrial wastewater treatments. The equilibrium adsorption capacity (q e ) found to be 48.1 mg.g À1 and 25.64 mg.g À1 for MB and DB-108, respectively. The adsorption takes place in only 5 min for both dyes. Moreover, the reusability of the Daps-POP was successful during three consecutive runs corroborating its promising application in industrial water treatment.
