摘要:
采用双波长分光光度法测定蜡质玉米淀粉中直链淀粉和支链淀粉含量//根据直链淀粉和支链淀粉与碘形成复合物的吸收光谱的差别,分别测定其含量。通过对两种淀粉测定的比较,支链淀粉的稳定性较差,建议采用双波长分光光度法直接测定直链淀粉含量。

摘要:
砷是当前环境中使人致癌的最普遍、危害性最大的物质之一,砷污染是指由砷及其化合物所引起的环境污染。大气中砷污染除岩石风化、火山爆发等自然原因外,主要来自工业生产及含砷农药的使用、煤的燃烧,在大气中有很长的驻留期并且可在生物体内沉积,长期接触低浓度的砷化物粉尘和气体,可发生慢性中毒、神经衰竭综合证、多发性神经炎、胃肠道症状、肝脏损害、皮肤黏膜病变等。

摘要:
重铀酸盐是核燃料循环的重要原料,对杂质含量要求严格,其中二氧化硅的含量是检验产品是否合格的一项重要指标。本工作采用硅钼蓝分光光度法对重铀酸盐中二氧化硅含量进行了测定。方法原理是低酸条件下氟离子与硅酸根反应生成氟硅酸,氟硅酸与钼酸铵生成硅钼黄杂多酸络离子,用亚铁将硅钼黄

摘要:
养鱼先养水,已成为水产养殖业者的共识,水质条件的优劣,直接影响养殖生物的健康。但目前池塘普遍采用高密度养殖,再经过夏季大量投喂,鱼体快速生长代谢,养殖水体中有机质大量累积,造成氨氮、亚硝酸盐等物质超标,导致水质恶化。如果以这种水质条件直接越冬,存在很大的风险,容易给养殖者带来巨大的经济损失。

摘要:
A novel thermal-assisted ultra-violet(UV) photocatalysis digestion method for the determination of total phosphorus(TP) in water samples was introduced in this work. The photocatalytic experiments for TP digestion were conducted using a 365 nm wavelength UV light and Ti O2 particles as the photocatalyst. Sodium tripolyphosphate and sodium glycerophosphate were used as the typical components of TP and the digested samples were then determined by spectrophotometry after phosphomolybdenum blue reaction. The effects of operational parameters such as reaction time and temperature were studied for the digestion of TP and the kinetic analysis of two typical components was performed in this paper. The pseudo-first-order rate constants k of two phosphorus compounds at different temperatures were obtained and the Arrhenius equation was employed to explain the effect of temperature on rate constant k. Compared with the conventional thermal digestion method for TP detection, it was found that the temperature was decreased from 120 °C to 60 °C with same conversion rate and time in this thermal-assisted UV digestion method, which enabled the digestion process work at normal pressure. Compared with the individual ultra-violet(UV) photocatalysis process, the digestion time was also decreased from several hours to half an hour using the thermal-assisted UV digestion method. This method will not lead to secondary pollution since no oxidant was needed in the thermal-assisted UV photocatalysis digestion process, which made it more compatible with electrochemical detection of TP.
