“…Although some methods such as chemical precipitation, membrane extraction, coagulation, complexing, solvent extraction, ion change, and adsorption have been developed, the economic and effective removal of these dyes is still a significant problem. Among these, adsorption is one of the popular methods for wastewater treatment on account of its easy and inexpensive operation [1][2][3].…”

“…The carboxyl group content of CNM samples was determined by the back-titration method (Jeon et al, 1999;Stojanović et al, 2005). Briefly, 50 mg of CNF suspension (0.2 wt%) was carefully added to 10 mL of 0.1 M NaOH maintained at 50 • C and stirred for 30 min.…”

This study describes a class of cellulosic nanomaterials, cellulosic nanowhiskers (CNWs), and demonstrates scaled-up production with acid recovery using less expensive equipment made of common stainless steel rather than glass-lined steel. CNWs produced using concentrated maleic acid (MA) hydrolysis followed by mechanical fibrillation have morphology similar to MA-produced cellulose nanocrystals (CNCs) and sulfuric-acid-produced CNCs (S-CNCs) but differ in crystallinity. Applications of CNWs as a substitute for CNCs for which morphology and surface charge, rather than crystallinity, are the pertinent characteristics are presented. The tested CNW suspensions have a wider viscosity range of 0.001 to 1000 Pa.s over a variety of shear rates of 0.01 to 1000 1/s compared to S-CNCs of 0.001 to 0.1 Pa.s and are better suited for applications such as rheology modification and 3D printing. This study proposes CNWs as a less expensive and sustainable replacement for CNCs in applications that do not require crystalline properties.

“…The controlled radical polymerization of DMAEMA would enable the control of the composition of the DMAEMA graft (through the reaction time/monomer conversion) and in addition should produce polymers with reproducible variation in size, in response to a stimulus. This amphiphilic graft copolymer has great promise in practical applications like stimulus behavior and in sorption chemistry [27][28][29][30][31]. The graft polymer is expected to act like a hydrogel material due to the presence of the hydrophilic DMAEMA and the hydrophobic backbone of polystyrene.…”
