“…Meanwhile, chemical processing can be performed using polystyrene compounds (90-95%) found therein. Several studies have modified polystyrene by chemically reacting it with chelating agents [6] or through a nitration reaction [7] and sulfonation [8,9]. This sulfonation reaction can change polystyrene, which is nonpolar, to be polar due to the addition of sulfonate groups.…”

The combination of polystyrene and chitosan can form polyelectrolyte (PE) membranes. Polystyrene sulfonate-chitosan (PSS-chitosan) adsorbent membrane can adsorb dodecyl benzene sulfonate (DBS) in laundry wastewater. This study aimed to synthesize, identify characteristics, and formulate adsorption effectiveness by PSS-chitosan membranes. The research methods included converting polystyrene into PSS, isolating chitosan, optimizing geometry, making PSS-chitosan membranes, studying adsorption, and applying membranes to laundry wastewater. The resulting membrane was characterized using FTIR and SEM. The results of the infrared spectra showed vibrations of –OH and –NH2 groups at 3418 cm–1, while the SEM image showed a homogeneous membrane surface. The quality of chitosan isolation from shrimp shells was indicated by the degree of deacetylation of 61.3%. The results of the geometry optimization showed the change in the structure’s total energy after adsorption. The PSS-chitosan membrane is resistant to acids but decomposes under alkaline conditions. Optimum adsorption of PSS-chitosan membrane on DBS occurred at pH 8 for 100 minutes. The adsorption kinetics of the PSS-chitosan membrane follows the first pseudo-order equation. PSS-chitosan membrane adsorption isotherm follows the Langmuir isotherm model with an adsorption capacity and efficiency of 3.97 mg.g–1 and 76.6%, respectively, at 0.6 ppm. At the application stage, the PSS-chitosan membrane could adsorb DBS in laundry wastewater by (62.4 ± 7.2) %.

“…6 Various techniques, such as flame atomic absorption spectrometry (FAAS), graphite furnace atomic absorption spectrometry (GF-AAS), inductively coupled plasma mass spectrometry (ICP-MS), inductively coupled plasma atomic emission spectrometry (ICP-AES), inductively coupled plasma optical emission spectrometry (ICP-OES), thermospray flame furnace atomic absorption spectrometry (TS-FF-AAS) and electrothermal atomic absorption spectrometry (ET-AAS), have been routenly used for the determination of total chromium. 7 Unfortunately these techniques cannot differentiate Cr(III) from Cr(VI) ions. For the speciation and preconcentration of chromium species, several methods based on solid-phase extraction (SPE), [8][9][10][11] coprecipitation, [12][13][14] cloud point extraction 15 and liquid phase microextractions [16][17][18] have been developed.…”

Amberlite XAD-4 resin (AXAD-4) was chemically modified to an aminated Amberlite XAD-4 (AAXAD-4) resin and characterized by infrared spectroscopy. AAXAD-4 resin was used as an efficient solid phase for the preconcentration and speciation of Cr(III) and Cr(VI) ions by column technique. The concentration of chromium species was determined by microsample injection system-flame atomic absorption spectrometer (MIS-FAAS). Selective retention of Cr(III) ions was achieved at pH 8.0 and eluted using 1.0 mL of 3.0 mol L-1 HCl and 1.0 mL of 2.0 mol L-1 NaOH, successively, at the flow rate of 5.0 mL min-1. The maximal sorption capacity of AAXAD-4 resin for Cr(III) ions was found to be 67.0 mg g-1. The limit of detection (LOD) and limit of quantitation (LOQ) for Cr(III) ions were found to be 0.041 and 0.131 µg L-1 , respectively, with preconcentration factor (PF) of 375 and relative standard deviation (RSD) of 3.75% (n = 11). The method was validated using certified reference materials (CRMs) and successfully applied to the real samples, spiked with Cr(III) and Cr(VI) ions.
