Nanoscale zero valent iron particles were synthesized by reductive method in aqueous phase. The crystal structure, morphology and size of the particles were characterized using X-ray diffraction and transmission electron microscopy. The influence of temperature, initial acid fuchsine concentration, nanoscale zero valent iron dosage and pH on the removal of acid fuchsine by the particles was studied, and the removal mechanism of acid fuchsine was discussed.

摘 要：采用液相还原法制备零价纳米铁粒子；用X射线衍射和透射电镜表征该样品的晶体结构、颗粒形貌与尺寸；研究温度、酸性品红初始浓度、纳米零价铁加入量及溶液pH值对零价纳米铁粒子脱除酸性品红的影响，并对酸性品红的脱除机理进行讨论。

The results show that the obtained nanoscale zero valent iron particles are mostly in spherical shape with less than 100 nm in size. The acid fuchsine can be removed by nanoscale zero valent iron particles efficiently. The efficiency of removing acid fuchsine from solution is increased with increasing temperature and the dosage of nanoscale zero valent iron particles and decreasing initial concentration of acid fuchsine. The mechanism of removing acid fuchsine by nanoscale zero valent iron particles may include dual functions of absorption and degradation, and the degradation may play a major role in the reaction.

研究结果表明：纳米零价铁颗粒为球形，单个颗粒粒径小于100 nm；纳米零价铁对酸性品红有很好的脱除作用，酸性品红的脱除率随温度的升高、纳米零价铁用量的增加以及酸性品红初始浓度的降低而逐渐增大；纳米零价铁对酸性品红有吸附和降解的双重作用，而以降解作用为主。

Simultaneously, the total extractible myoglobin decreased and the proportion of metmyoglobin increased significantly when the pressure above 400MPa. Beef discoloration after pressure processing may result from oxidation of ferrous myoglobin to ferric metmyoglobin, globin denaturation and structural changes. At 40℃, the changes of beef color was similar to that of room temperature's. When the temperature rise to 60℃, most of muscle proteins denatured, a small quantity of native myoglobin could not affect the color of beef significantly. Therefore, protein denaturation was attributed to the main cause of discoloration in beef muscle after pressurization at 60℃.

压力处理导致色泽变化的直接原因可能是由于二价铁的肌红蛋白氧化成三价铁的高铁肌红蛋白、球蛋白的变性及结构的变化所致。40℃时的压力处理，色泽的变化规律与室温下相似，只是色泽变化的程度更为剧烈，蛋白质变性在色泽变化中起到的作用逐渐加强。60℃下的压力处理，绝大部分蛋白质发生变性，少量未变性的肌红蛋白对色泽不会产生明显的影响，此温度的压力处理，蛋白质变性是造成肌肉失去红色的主要原因。

The experimental results indicates that the optimum pH range was 1.60~2.20, and the optimum H2O2 concentration was 10.0 mmol/L. The degradation ratio increased with the increasing concentration of ammonium ferric oxalate in the range from 0.1 to 1.0 mmol/L, but no significant increase in degradation ratio was observed when the concentration was above 1.0 mmol/L. When the concentration of fuchsin basic increased, the degradation ratio dropped, while the concentration of degraded fuchsin basic rised. When the concentration of fuchsin basic was low, the degradation followed first-order kinetics, but when it was high, the degradation could be fitted by zero-order kinetics. The absorbtion of fuchsin basic at 543 nm disappeared quickly, while the absorbtion of intermediates formed during the course of fuchsin basic dagradation at 298 nm vanished slowly.

试验结果表明：碱性品红降解的最佳初始pH为1.60~2.20，最佳初始H2O2浓度为10.0mmol/L；草酸高铁铵的浓度在0.1~1.0mmol/L时，碱性品红的降解率随浓度的增大而增大；高于1.0mmol/L时，则降解率相差不大；碱性品红的初始浓度增大，降解率减小，而实际降解的浓度则增加；碱性品红的浓度在低和高时，降解动力学过程不一致；随降解的进行，碱性品红在可见光区的吸收峰迅速消失，而降解过程中形成的中间产物吸收峰却消失很慢。
