在传统的软化工序中,为了除去无用残留物,通常使用从猪或牛胰腺中分离提取的的胰酶。一般来说,软化工序结束后,浴液的酶不能重复利用,被排放到废水中。由于这些错误,软化工序增加了额外的废水处理费用。纳米粒子有较大的表面积和较自己的体重高数百倍的结合容量。他们也可以通过染料载体使用非纤维蛋白的吸附。通过这种方式,我们研究了染料亲和纳米颗粒代替酶软化过程。在这项研究中,p(HEMA)(2-羟基乙基甲基丙烯酸酯)纳米颗粒通过表面活性剂乳液自由聚合产生。P(HEMA)纳米粒子的特性通过傅里叶变换红外光谱(FTIR)和扫描电子显微镜(SEM)表征。三嗪染料活性红120通过化学方法附加到p(HEMA)纳米粒子。这些染料包含p(HEMA)-活性红120具有亲和力的纳米颗粒,用于在水溶液中非纤维蛋白质的吸附。此外优化了p(HEMA)-活性红120在间歇反应器的实验条件和其吸附容量。结果证明了纳米颗粒的可重用性和其作为软化剂的有效性。因此,和软化工序中的酶相比,p(HEMA)-活性红120纳米粒子是一种环境友好的、廉价的、可重复使用的材料。
In traditional softening procedures, trypsin isolated from pigs or bovine pancreases is commonly used to remove unwanted residues. In general, the end of the softening process, the bath of the enzyme can not be reused, was discharged into the wastewater. Due to these errors, the softening process adds extra costs for wastewater treatment. Nanoparticles have a larger surface area and hundreds of times more binding capacity than their own. They can also use non-fibrin adsorption through the dye carrier. In this way, we studied dye affinity nanoparticles instead of enzyme softening process. In this study, p (HEMA) (2-hydroxyethylmethacrylate) nanoparticles were produced by free-radical polymerization of surfactant emulsions. The properties of P (HEMA) nanoparticles were characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). Triazine dye Reactive Red 120 is chemically attached to p (HEMA) nanoparticles. These dyes contain p (HEMA) - Reactive Red 120 nanoparticles with affinity for adsorption of non-fiber proteins in aqueous solution. In addition, the experimental conditions and adsorption capacity of p (HEMA) - Reactive Red 120 in a batch reactor were optimized. The results demonstrate the reusability of the nanoparticles and their effectiveness as softeners. Thus, p (HEMA) - Reactive Red 120 nanoparticles are an environmentally friendly, inexpensive, reusable material compared to enzymes in the softening process.
