Liu et al. developed a method to extract pure lignin from Tobacco stalks using a hydrothermal process with phosphotungstic acid to selectively remove hemicellulose. The hydrothermal process occurs at 170 °C for 1 hour, while the pretreatment with 1% (w/v) phosphotungstic acid occurs at 130 °C for 1 hour. Following these steps, an alkali treatment with 14% NaOH and 0.5% Anthraquinone is performed to extract lignin through black liquor.
