Method & Evidence

AimTo determine the optimal retting duration and multi-step alkaline peroxide process parameters for maximizing cellulose yield and quality from Ethiopian linseed straw.

MethodExperimental Design (Taguchi Method) and Gravimetric Analysis, FTIR Spectroscopy, Thermal Analysis

ProcedureLinseed straw was subjected to varying retting durations at room temperature. Subsequently, the retted fibers underwent a multi-step extraction process involving solvent treatment (ethanol-toluene), alkaline treatment (NaOH), and peroxide treatment (H2O2), with parameters like concentration, temperature, and time systematically varied according to the Taguchi design. Cellulose yield was quantified gravimetrically, and fiber characteristics were analyzed using FTIR and thermal studies.
