Bashar Dan-asabe

Hello Juan-Rodrigo, I'm unable to see any useful/related info with respect to my question. Could you please recheck the title of the article you provided? Specifically, I'm interested in knowing the lignocellulosic chemical composition of doum palm fibre i.e. percentage composition of its cellulose, lignin, pectin, mineral and water contents.

Additionally, I want to know which equipment that I can use to determine to this (determine the percentage composition).

Leigh Aldous

TAPPI and NREL provide standardised procedures for quantifying the composition of lignocellulosic materials.

i.e. cellulose + lignin = http://www.nrel.gov/biomass/pdfs/42618.pdf

TAPPI address the components individually (e.g. lignin = http://www.tappi.org/content/SARG/T222.pdf), and refer to other relevant reports inside the report. There are a lot of these procedures - http://www.tappi.org/content/pdf/standards/numeric_index_tms.pdf !

At the very least, you will need a balance, conc. H2SO4 (and the ability to handle it safely!), the ability to heat the acid, and decent filtration equipment. Ideally you will have access to a furnace and crucibles (or TGA), UV-Vis spectrophotometer and a Soxhlet extractor (from memory).

I've put a link below to one of my papers which describes the whole approach to determining cellulose, hemicellulose, lignin and ash: https://www.researchgate.net/publication/281345782_Facile_room-temperature_pre-treatment_of_rice_husks_with_tetrabutylphosphonium_hydroxide_Enhanced_enzymatic_and_acid_hydrolysis_yields
