| Abstract | ||
| Date palm (Phoenix dactylifera L.) is considered as an important crop in the Arabian Gulf. Lot of date palm leaves and rachis were collected annually and considered waste that causes problem for the environment. In this work, the cellulose fiber was isolated from two by-products of the date palm tree, rachis, and leaflets by acid hydrolysis and bleaching treatments. The isolated cellulose fiber was modified by grafting with acrylamide to convert into composite polymer to use in the purification of waste water. There are numerous advantages to using isolated cellulose fiber and its composite polymer. This fiber is widely used in modern industries and has replaced conventional materials due to their high specific strength, light weight, low cost, recyclability, biodegradability, and long durability. All prepared samples were characterized by Fourier transform infrared, X-ray diffraction, the energy dispersive X-ray and scanning electron microscopy. The results obtained indicate that the percent of cellulose was increased and the percent of lignin and hemicellulose was decreased after the isolation and bleaching processes and the cellulose fiber obtained from date palm by-products characterized by high crystallinity. Grafted samples copolymers were used in removal of methyl orange from waste water to study the role of cellulose grafted samples in purification of it as an application in our study. The maximum adsorption of MO occurs at pH 3.0 after 15 h, and the maximum adsorption capacity calculated from Langmuir is 48.12 mg/g. Date palm fibers considering as a promising alternative substitute to synthetic fibers in polymer composite industry. | ||
