Enhancement of acidic dye biosorption capacity on poly(ethylenimine) grafted anaerobic granular sludge

Facile synthesis and in situ magnetization of carbon‐decorated lignocellulose fiber for highly efficient removal of methylene blue

“…As shown in Fig. (d), the maximum adsorption capacity of mC@LCF is found to be 341.2 mg g −1 at 313.15 K. Taking into account the fact that the removal of dyes, in practice, is generally performed at room temperature, we used the adsorption capacity value 232.2 mg g −1 at 303.15 K to compare with those obtained by other adsorbents. Nevertheless, mC@LCF showed a much higher MB removal capacity than those of other adsorbents, indicating its high performance for the removal of organic dyes in aqueous solution.…”

Emission characteristics of nitrogen- and sulfur-containing odorous compounds during different sewage sludge chemical conditioning processes

“…The N 1s peak is resolved into three component peaks which achieved an acceptable fit in the XPS spectra. The binding energy values at 401.5 ± 0.6 eV, 400 ± 0.2 eV, 398.6 ± 0.2 eV can be assigned to N H in ammonia or protonated amine, N O/C N in amide or amine, and nitrogen in amine groups ( N ), corresponding to N 1 , N 2 , N 3 , respectively [22][23][24].

Tea Stem as a Sorbent for Removal of Methylene Blue from Aqueous Phase

“…Solving the dye-induced pollution problem is increasingly crucial. Current methods to dyestuff wastewater treatment include coagulation, advanced oxidation, membrane separation, biodegradation, and adsorption [10][11][12][13][14], all of which were limited to apply in industries because of more chemical consumption, complex operating conditions, and second pollution [15][16][17][18]. Adsorption, however, has advantages such as low cost, environmental safety, regeneration, and easy operational feasibility when compared with other methods, which attracts people to explore new approaches to solve the dyestuff wastewater problem [6,7,19].…”
