Abstract

Sodium carboxymethyl cellulose is a type of macromolecular chemical substance that is widely used in the industry for food thickening. In this study, terahertz and microfluidic technologies were combined, and a microfluidic chip with a channel depth of 50 μm was fabricated to carry samples. The terahertz characteristics of the sodium carboxymethyl cellulose colloid were studied at different concentrations and applied electric fields. The obtained results showed that different concentrations of sodium carboxymethyl cellulose have different time-domain spectra; with an increase in concentration, the terahertz transmittance of sodium carboxymethyl cellulose decreased. Under the applied electric field treatment, the longer the electric field acting time is, the higher the terahertz transmission intensity is. This approach is a safe and reliable new method for the determination of sodium carboxymethyl cellulose concentration, which provides technical support for the in-depth study of sodium carboxymethyl cellulose.

基于微流控技术的羧甲基纤维素钠胶体的太赫兹吸收特性

羧甲基纤维素钠是一种广泛应用于食品增稠的大分子化学物质。在这项研究中，太赫兹和微流体技术相结合，制作了一个通道深度为50的微流体芯片 μm来携带样品。研究了羧甲基纤维素钠胶体在不同浓度和外加电场下的太赫兹特性。结果表明，不同浓度的羧甲基纤维素钠具有不同的时域光谱；羧甲基纤维素钠的太赫兹透过率随浓度的增加而降低。在外加电场处理下，电场作用时间越长，太赫兹传输强度越高。该方法是一种安全可靠的羧甲基纤维素钠浓度测定新方法，为羧甲基纤维素钠盐的深入研究提供了技术支持。
