한국산토탄의 흄산의 성상과 그 응용(전답용토양개량제 및 용성인질비료제조 아조염료의 제조에 관해서 보고한 바와 같이 8개의 페놀성 -OH기를 가진 흄산의 구조로 보아서 황화염료의 제조원료가 될수 있을 것으로 보고 그 제조조건, 염색물의 견착도, 제조된 황화염료의 구조를 고찰해서 유휴자원인 토탄에 대한 하나의 활용책을 강구하였다.

Sulfur-dyes were manufactured from humic acid, Na2S2∼3 and other additives at 200∼250℃ for 3∼20 hrs. Sulfur-dyes from humic acid were fundamentally brown colors and could be changed from yellowish to grayish brown according to the additives. The colorfastness to rubbing and laundering were excellent but to weather was fair. Characteristic bonds of sulfur-dyes such as -C-S-C, -C-SO-C-. -C-SO2-C-, and -C-O-SO2-O-C- were confirmed but thiazole bond and thiazine ring were not done by IR-spectroscopy.
