Zusammenfassung:The invention relates to a multifunctional cellulose-based sulfur quantum dot and application thereof. The preparation method of the sulfur quantum dot comprises the following steps: fully dispersing sublimed sulfur powder and carboxymethyl cellulose in an alkaline solution to obtain a dispersion liquid, then introducing oxygen, carrying out a heating reaction, and carrying out post-treatment to obtain the sulfur quantum dot. The preparation method is simple and feasible, and the raw materials are economical; the prepared cellulose-based sulfur quantum dots have multiple functions of fluorescence, bacteriostasis, tracing and the like. According to the invention, sulfur quantum dots are applied to calcium sulfate inhibition and bacteriostasis tests, so that the sulfur quantum dots have excellent bacteriostasis, scale inhibition and dispersion effects in circulating cooling water, and have a good market application prospect. 本发明涉及一种多功能性纤维素基硫量子点及应用。本发明硫量子点的制备是将升华硫粉、羧甲基纤维素充分分散在碱性溶液中得到分散液,然后通入氧气加热反应经过后处理即得。本发明制备方法
