Adsorption Mechanism of Nonylphenol Polyethoxylate onto Hypercrosslinked Resins

Removal of nonylphenol ethoxylate from laundry wastewater using modified and functionalized activated carbon

“…Several factors affect the adsorption of NPEO from aqueous solutions, including the specific surface area and the pore size of the adsorbent. 14 It was found that the surface area of pores larger than 1.5 nm is crucial to the adsorption capacity of NPEO. Consequently, NPEO molecules might mainly adsorb on pores with a diameter greater than 1.5 nm.…”

“…Particle interaction may also desorb some sorbate that is only loosely and reversibly bound to the carbon surface. 67 The COD removal and adsorption capacity show the same trend as NPEO [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] . By comparison to NPEO 3-17 removal, and as shown in Fig.…”

“…13 Other groups used synthetic resins for the adsorption of NPEO 10 and their subsequent removal from aqueous solutions. 14,15 Mostafazadeh et al (2019) employed various integrated treatments, including ultrafiltration followed by adsorption using resin and activated carbon, to eliminate NPEO 3–17 from real laundry wastewater. 16 In another study, researchers explored the effectiveness of employing a submerged membrane filtration system in combination with powdered activated carbon to remove NPEO 1–15 .…”
