抄録

The purpose of this study is to examine dissolved organic matter (DOM) removal using charcoal made from Japanese cedar wood (<i>Cryptomeria japonica D. Don</i>). We used three types of charcoals carbonized at 450, 650, and 1050°C to compare their DOM removal rate and removal volume. The removal rates of DOM contained in rice-straw water and the DOM-fraction distribution in treated water were studied in laboratory experiments. The results showed that the charcoal at 1050°C (C1050) markedly removed DOM from rice-straw water. C1050 removed of 70% DOM in 48 h. UV (260 nm) absorbance, which can be used for the index of recalcitrant DOM concentration, decreased to 30% with C1050 treatment. DOM fractionation in treated water in 48 h showed that C1050 removed 97% of the hydrophobic acid contained in recalcitrant DOM. The molecular weight distribution showed that C1050 removed high-molecular-weight compounds including humic substances.
