Preparation of Pineapple Leaf Cellulose Membrane

Advanced Materials Research, 2014
In this study, the pineapple leaf cellulose membrane was prepared after being dissolved in ionic liquid (1-butyl-3-methylimidazolium chloride ([Bmim]Cl)) and high pressure microfluidization process. The chemical morphology and structure of cellulose membrane were measured by scanning electron microscope (SEM), fourier transformed infrared spectra (FT ...

Chemical modification of pineapple leaf fiber: Graft copolymerization of acrylonitrile onto defatted pineapple leaf fibers

Journal of Applied Polymer Science, 2000
Graft copolymerization of acrylonitrile (AN) onto defatted pineapple leaf fiber (PALF) was studied using a CuSO4 and KIO4 combination as an initiator in an aqueous medium in the temperature range 30–500C. The effects of the concentration of potassium periodate, CuSO4, and monomer on the graft yield were investigated.

Modification of pineapple leaf fibers with aminosilanes as adsorbents for H2S removal

Chemosphere, 2021
Pineapple leaves were used as a natural fiber source to prepare various modified microcrystalline cellulose (MCC) samples as sorbents for H2S sorption. Pineapple leaf fibers were first extracted from pineapple leaves, followed by hydrolyzing to produce MCC before various modifications using primary amine (3-aminopropyltrimethoxysilane, APS), secondary ...
