Selective removal of phenolic lignin derivatives enables sugars recovery from wood prehydrolysis liquor with remarkable yield

•Binding of calcium ions to phenolic lignin leads to lignin precipitation.•Lignin removal occurs at pH higher enough for lignin ionization but not sugar.•Lime treatment facilitates enhanced uptake of lignin by anion exchange resin.•Lime-resin treatment results in 95% lignin removal and 78.8% sugar r...
