    Investigation onto Local Palm Tree Fibers : Characterization and Applications
    (جامعة سبها, 2023) Dua, Alamani; Hissen, ALaraby; Salim, Fatimah
    Palm fibers and all natural fibers provide new opportunities for industry, especially when managing waste disposals are of great concerns for the environment. This has led to increasing pressure to recycle materials at the end of their useful life. In this research, palm fibers were collected from five (5) types of palm trees planted in Sebha city region. These natural fibers and some palm dates as well as some portions of soils collected from regions near the same palm trees were studied using (XRF). The analysis was performed on the fibers, dates and soils in order to identify their elements that make them up and properties. It was surprising to find that the palm fibers, the dates, and the soils contain almost similar elements such as Si, Ca, K, Al etc. and even heavy metals such as Fe, Ti and Ni etc. Following such analysis, two different experiments were carried out to explore more useful applications for palm fibers. In the first experimental phase, bioplastic was prepared following an experiment that consists of three steps. The first step was to prepare (NaOH). In the second step, it is called bleaching. In the last step, the bioplastic was prepared, after which the sample was cast and dried in aluminum molds at room temperature. In the second experimental phase, Nano-material (COFe2O) was prepared and used with palm fibers as an environmentally friendly material in the tests of removing crude oil from sea water. This was done by using magnets with proportions (0.04% ) of palm fibers and Nano-material. Very promising results were obtained when palm fibers were utilized as composite materials in plastic and crude oil removal applications.
