Effects of alkali treatment on mechanism of extrusion bonding of eucalyptus wood fiber

Peng Wanxi,Lin Zhi and Li Niancun

Strategic Study of CAE 2014, Volume 16, Issue 4,   Pages 64-68

Abstract:

Eucalyptus wood fiber was prepared to investigate the effects of alkali treatment on mechanism of extrusion bonding of the board. The results showed that hemi-cellulose and lignin were partly degraded during eucalyptus wood fiber were treated with alkali，these degraded substances could be copolymerized during hot-pressing，the influence of alkali (NaOH) on eucalyptus wood fiber was greater than the weak base (Na2CO3) and the processing time for 10 h was more appropriate，and the increased hydroxyl after defibrinating partly formed hydrogen-bonding during hot-pressing，resulting in strengthened fiber self-bonding.

Application and mechanism of polysaccharide extracted from Enteromorpha to remove nano-ZnO and humic acid in coagulation process

Jianzhang Sun, Baoyu Gao, Yuanxia Luo, Moxi Xue, Xing Xu, Qinyan Yue, Yan Wang

Frontiers of Environmental Science & Engineering 2018, Volume 12, Issue 3, doi: 10.1007/s11783-018-1029-8

Abstract: Enteromorpha polysaccharide (Ep) extracted from alga a novel green coagulant aid for nanoparticles (NPs) and heavy metal ions removal and the structure of EP was intensively studied in this study. The integration of Ep with polyaluminum chloride (PAC-Ep) coagulants exhibited higher coagulation performance than that of the polyaluminum chloride (PAC) because of the negatively charged NPs suspension and humic aid (HA) solution. Significant high removal efficiencies of dissolved organic matter (94.1%), turbidity (99.3%) and Zn ions (69.3%) were achieved by the PAC-Ep coagulants. The dual-coagulation properties of PAC-Ep for different pollutants was based on multiple mechanisms, including (i) Al charge neutralization; (ii) hydroxy aluminum hydroxyl bridging formed polynuclearhydroxy complexes bridge and sweep colloidal particles; (iii) adsorption and bridging of Ep chain for the NPs and heavy metal ions. Results indicated that the destabilization of colloid was induced by the coexisting HA and higher removal was achieved as ions adsorption was enhance in the presence of HA complexation. On the basis of that, the extraction of polysaccharide is a promising candidate for its high coagulation performance in water treatment.
