Abstract

The widespread use of petroleum-based products has led to increasing environmental and ecological problems, while the extraction and application of various natural cellulose fibers have received increasing attention. This research focuses on the extraction of cellulose fibers from cow dung using different treatments: hot water, hydrogen peroxide (HO), sodium hydroxide (NaOH) and potassium hydroxide (KOH) boilings, as well as a selection of the best quality cow dung fibers for papermaking with quality control. The study's objective is to find a sustainable method to extract as much material as possible from renewable biomass feedstock. The results show that the best extraction rate is obtained by KOH boiling with 42% cellulose fibers extracted. Corresponding handmade paper has a burst index of 2.48 KPam/g, a tear index of 4.83 mNm/g and a tensile index of 26.72 Nm/g. This project expands the sources of natural cellulose fibers to an eco-friendly and sustainable one and opens up new applications for cow dung.

摘要

石油基产品的广泛使用导致了日益严重的环境和生态问题，与此同时，各种天然纤维素纤维的提取和应用受到了越来越多的关注。本研究聚焦于采用不同处理方法从牛粪中提取纤维素纤维，这些方法包括热水处理、过氧化氢（HO）处理、氢氧化钠（NaOH）煮沸处理和氢氧化钾（KOH）煮沸处理，同时还对造纸用的优质牛粪纤维进行了质量筛选和控制。该研究的目的是找到一种可持续的方法，从可再生生物质原料中尽可能多地提取物质。结果表明，通过KOH煮沸处理获得的提取率最高，提取出了42%的纤维素纤维。相应的手工纸的耐破指数为2.48千帕·米/克，撕裂指数为4.83毫牛·米/克，拉伸指数为26.72牛·米/克。该项目将天然纤维素纤维的来源拓展至一种环保且可持续的资源，并为牛粪开辟了新的应用领域。
