In the present study, cellulose colloids are treated with the solution plasma process in order to prepare reducing sugar. The investigated parameters are treatment time, type of electrodes, and applied pulse frequency of the bipolar supply. The reducing sugar was characterized by DNS method and the%yield of total reducing sugar (TRS) was then calculated. The crystal structure and chemical structure of plasma-treated cellulose was measured by XRD and FT-IR, respectively. The%yield of TRS was greatly enhanced by solution plasma treatment using Fe electrode. SEM and TEM micrograph indicated that Fe electrode yield the incidental Fe nanoparticles, hypothesized to catalyze the cellulose degradation during SPP treatment. The crystal structure of cellulose was destroyed. Solution plasma treatment of cellulose using Fe electrode at the high applied frequency pulse provided the highest%TRS.
在本研究中，采用溶液等离子体工艺处理纤维素胶体以制备还原糖。研究的参数是处理时间、电极类型和双极性电源的施加脉冲频率。用 DNS 法对还原糖进行了表征，然后计算了总还原糖（TRS）的产率。用 XRD 和 FT-IR 分别测量了等离子体处理纤维素的晶体结构和化学结构。使用 Fe 电极的溶液等离子体处理大大提高了 TRS 的产率。SEM 和 TEM 显微照片表明，Fe 电极产生了偶然的 Fe 纳米粒子，据推测，在 SPP 处理过程中可以催化纤维素的降解。纤维素的晶体结构被破坏。在高施加频率脉冲下使用 Fe 电极对纤维素进行溶液等离子体处理，提供了最高的%TRS。
