Depending on the method of cellulose production, proportion alpha fraction in it can vary significantly. Paper pulp, unlike dissolving cellulose, has an less than 90%. The presence satellites system does not impede formation concentrated solutions N-methylmorpholine-N-oxide (NMMO). In current study, spinning based with a low (up to 90%) (pulp cellulose) are investigated. morphological features and rheological behavior such examined. It is suggested roll obtained order obtain membranes. X-ray...
The separation of used engine oil (UEO) with an ultrafiltration (UF) membrane made commercial copolymer poly(acrylonitrile-co-methyl acrylate) (P(AN-co-MA)) has been investigated. P(AN-co-MA) sample was characterized by using FTIR spectroscopy, 13C NMR and XRD. UF a mean pore size 23 nm fabricated non-solvent-induced phase method—the casting solution 13 wt.% in dimethylsulfoxide (DMSO) precipitated the water bath. Before experiment, diluted toluene, resulting UEO toluene (100 g/L) filtered...
In this study, ultrafiltration membranes were developed via a nonsolvent-induced phase separation method for the removal of asphaltenes from crude oil. Polyacrylonitrile (PAN) and acrylonitrile copolymers with acrylic acid used as membrane materials. Copolymerizing resulted in an improvement fouling resistance membranes. The addition 10% to polymer chain decreases water contact angle 71° 43°, reducing both total irreversible compared made PAN homopolymer. obtained pore size 32–55 nm...
The process of nanofiltration purification water from various organic pollutants was examined. Cellophane film made cheap natural raw materials used as a membrane. model substances targeted for removal were dyes (Safranin O, Orange II, and Remazol Brilliant Blue R, each differing in molecular weight, chemical composition, charge) ceftriaxone. obtained cellophane permeability to 0.145 kg/(m2∙h∙atm). membranes found be effective retaining dissolved anionic containing acid groups. When II R...
