　A study was made about the adsorption of methylene blue from methanol by sulfonated peat humic acid and other peat humic acid derivatives. The results were as follows. The adsorbability of sulfonated peat humic acid，which was prepared on the reaction of humic acid with H_2S0_4-BF_3 complex at 150℃ for 90 min.，was　evaluated at about 230 mg/g for　methylene　blue. However，the　adsorbability of　epoxydated　and chloropropano humic acid derivatives showed lower values in comparison with the original humic acid. Sulfonated peat humic acid　showed　adsorption under　Freundlich's　isotherm and might be of chemical character. The humic acid became insoluble in alkali solution by sulfonation and the sulfonated humic acid was also insoluble in several other organic solvents
