Practicability of advanced and innovative techniques facilitates the high yield of cellulose extraction within a short period. The research aimed at the extraction of naturally abundant cellulose from Acer platanoides by “Nitrogen protected microwave assisted extraction (NPMAE)”. The NPMAE uses microwaves for heating the sample and helps in fast extraction of cellulose in the presence of nitrogen atmosphere. Cellulose extraction was intensified by bleaching treatment in closed multimode NPMAE system at 100 W and 120 °C for 15 min. Experiment's result found that Acer platanoides fiber contains 70% cellulose content and diffferent analysis were studied for all chemically pre-treated fibers and found variations in results after each chemical treatment. The SEM results of bleached fibers show the rough surface due to the removal of lignin and hemicellulose. XRD pattern and FTIR analysis are in the favor of cellulose extraction and results show the presence of type I cellulose with 65% crystallinity index whileTGA and dTGA results explain that cellulose of Acer platanoides bleached fibers (APBF) is more thermally stable below 370 °C than other pre-treated fibers. [Display omitted] •The Acer platanoide stalk's fiber contains 70% cellulose and intensified by bleaching treatment.•The bleaching conducted via N2-protected microwave assisted extraction.•The SEM and FTIR analysis explore the presence of cellulose in bleached fiber (BF).•The XRD pattern certifies 65% crystalline nature and compactness of cellulose in BF.•The TGA proved that cellulose of APF-BF is more thermally stable below 370 °C.
