Extraction and characterization of fulvic acid from oil palm empty fruit bunches

Menara Perkebunan
Oil palm empty fruit bunches (OPEFB) contain 27.78% lignin, which can serve as an alternative source of renewable fulvic acid, alongside soil and coal. This study aims to conduct the fulvic acid extraction process using a microwave extractor.
