Synthesis of a novel oil‐absorption resin and optimization of its performance parameters using response surface design

Abstract

A novel porous oil absorbing resin with the main monomers of stearyl methacrylate and isooctyl methacrylate was synthesized using suspension polymerization. The synthesis experiments were conducted using the response surface design method. And the influences of initiator concentration, cross‐linker concentration, and dispersant concentration were investigated. Through analyzing the second‐order polynomial mathematical models and the corresponding data, the mutual effects between these factors on the oil‐absorption performance were obtained. The response surface was used to analyze the oil (gasoline, diesel, and kerosene) absorption performance in the pure oil samples and oily water samples, respectively. The content of initiator and cross‐linker exhibited a necessary effect on the absorption of gasoline and kerosene. Moreover, the two most significant factors for diesel are the amount of initiator and dispersant. The experimental results showed that the oil‐absorbing resin synthesized under the optimized condition could achieve better oil‐absorption rate on all three oils. The absorption rates of gasoline, diesel, and kerosene are 10.14, 10.73, and 11.69 g/g, respectively, which the deoiling rate can reach closed 100% in the water sample containing gasoline and kerosene.

Preparation of porous poly(4‐tert‐butylstyrene) based monoliths with high efficiency for oil‐water separation via high internal phase emulsion template

“…Therefore, we have only explored here an internal phase volume fraction of 95%. From the comparisons in Table 3, the poly( t BS‐ co ‐DVB) obtained in this work showed the higher oil adsorption capacity than the reported adsorbents 39–43 …”

Preparation of a composite of polyacrylate and nano‐SiO2 particles and evaluation of its performance of oil–water mixture treatment

“…Figure 2A shows the FTIR spectra of SiO 2 before and after hydrophobic modification. The absorption peak of curve (b) in Figure 2A at 1633 cm À1 was attributed to the bending vibration of C C. 24 Curve (b) in Figure 2A exhibited three peaks at 2960, 2842 and 1409 cm À1 , corresponding to the Si CH 3 symmetric stretching vibration, Si-CH 3 asymmetric stretching vibration and Si CH 3 bending vibration, respectively. 25 The hydroxyl groups on the surface of SiO 2 were replaced by VTMS hydrolysates.…”

Time and volume‐ratio effect on reusable polybenzoxazole nanofiber oil sorption capacity investigated via machine learning

“…Few studies explored oil sorption by using statistical models, particularly the response surface design model 53–55 and regression model 56 . In recent studies IF‐THEN rules in fuzzy models have been applied extensively to analyze adsorption 57 and removal efficiency 58,59 in nanocomposite studies.…”
