Extraction, Characterization, and Comparison of Properties of Cassava Bagasse and Black Seed Fibers

ABSTRACT

The current study presents a nontoxic, and low-cost preparation of black seeds and cassava bagasse fibers. It also aims at investigating the physical, thermal, and morphological characteristics and chemical composition of these fibers. The current study’s findings revealed significant differences in the properties in terms of chemical, morphological, physical, and thermal. The findings also showed that black seed fiber had a higher ash concentration (4.5%) compared to the cassava bagasse fiber of 0.4%. A density of 1.45 g/cm³ was observed for cassava bagasse fiber, while the black seed fiber exhibited a lower density of 1.22 g/cm³. From TGA results, only 21% of cassava bagasse and 38% of black seed fiber weight were observed for the highest degradation rates for both samples (200°C–500°C). In summary, this study suggests cassava bagasse and black seed fibers as promising feedstocks for biopolymers synthesis with an eco-friendly and cost-effective approach that may support the advancement of the biopolymer industry.

摘要

目前的研究提出了一种无毒3001低成本的黑籽和木薯蔗渣纤维制备方法. 它还旨在研究这些纤维的物理、热、形态特征和化学成分. 目前的研究结果显示, 在化学、形态、物理和热性能方面, 这些特性存在显著差异. 研究结果还表明, 黑籽纤维的灰分浓度(4.5)高于木薯蔗渣纤维(0.4%). 木薯蔗渣纤维的密度为1.45 g/cm3, 而黑籽纤维的密度较低, 为1.22 g/cm3. 根据TGA结果, 两种样品(200°C–500°C)的最高降解率仅为21%的木薯蔗渣和38%的黑籽纤维重量. 总之, 这项研究表明木薯蔗渣和黑籽纤维是一种有前途的生物聚合物合成原料, 具有环保和成本效益, 可能支持生物聚合物行业的发展.
