Do the research of acidic zinc chloride treatment system to achieve poplar APMP with chemical swelling. The research showed that acidic zinc chloride can effectively swelling poplar APMP pulp, increase the fiber volume and loose the structure, acting concentrated in the amorphous region of the fiber which can help the penetration of chemicals and products of the dissolution. Because the differences of processing system pH and ionic effect, acidic zinc chloride combined alkaline hydrogen peroxide treatment can produce swelling synergistic effect.

Environmental concerns due to excessive use of synthetic or petroleum-based materials have encouraged scientists to develop novel, sustainable, and multifunctional material using abundant lignocellulosic biomass. In this work, a study was conducted on the isolation of cellulose from wheat straw using two different methods: acidified sodium chlorite and alkaline hydrogen peroxide. A comparative study was carried out based on the yield and properties of extracted cellulose. The final product (after treatments) was characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and thermogravimetric analysis (TGA) for the identification of properties. Both the treatments isolated pure white color cellulose. However, the yield of cellulose isolated through acidified sodium chlorite treatment (81.4%) was higher than alkaline hydrogen peroxide treatment (79%). Moreover, no huge difference was observed in the crystallinity and thermal properties of extracted cellulose.
