Preparation of Cationic Cellulose as a Natural Flocculant/Sorbent and Its Application in Three Water Treatment Scenarios
نویسندگان
چکیده
In this study, cationic cellulose (CC) was prepared by etherifying commercial with (3-chloro-2 hydroxypropyl) trimethylammonium chloride (CHPTAC) in an alkaline medium. The CC characterized using Fourier transform infrared spectrometry (FTIR), scanning electron microscopy (SEM), differential calorimetry (DSC), and nuclear magnetic resonance (NMR). characterization results affirmed the successful cationization of cellulose. Upon optimization reaction conditions, a sample degree substitution (DS) 0.857 achieved. then tested as flocculant or sorbent three environmental applications: algal harvesting, solid removal from dairy wastewater, capture methyl orange (MO) dye wastewater. effects dose level pH on flocculation/sorption performance were studied. Under optimal up to 90.4% dry biomass 53.3% suspended solids wastewater removed, measured standard jar testing. Around 64.2% MO synthetic sorbed determined absorbance at 463 nm. new preparation method exempts pre-dissolution solvent is expected promote application water treatment alike scenarios.

a comparative study of the theme of "marriage" in three victorian novelists: charles dickens, george eliot and thomas hardy
این تحقیق کوشیده است با انتخاب پنج رمان از میان آثار برگزیده، «چارلز دیکنز»، «جورج الیوت» و «توماس هاردی » و با رویکردی تطبیقی به بررسی درونمایه ی «ازدواج» در آثار این سه رمان نویس بزرگ دوره ی ویکتوریا بپردازد. فرضیه ی اولیه ی تحقیق این بوده است که چارلز دیکنز (1870- 1812) با زبانی شوخ و گزنده، جورج الیوت(1880- 1819) با نگاهی آموزشی–اندرزگونه و توماس هاردی(1928- 1840) با رویکردی تلخ وانتقادی به...

like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
