A novel catalytic resonance light scattering method for the determination of traces of formaldehyde in blood plasma was developed. It was based on the fact that potassium bromate reacted with pyronine Y to form association nanoparticles which gave stronger resonance light scattering effect, and formaldehyde can catalyze potassium bromate oxidizing pyronine Y resulting in decreasing of the intensity of resonance light scattering in sulfuric acid.
在稀硫酸介质中,溴酸钾与吡啰红Y能聚集成较大粒径的纳米微粒而使共振光散射增强,而甲醛能催化溴酸钾氧化吡啰红Y而导致体系共振光散射减弱,据此建立了一种灵敏、简单、快速测定血浆中痕量甲醛的新方法。

The function mechanism among the minerals and floatation drugs had been studied with the way of IR and academic calculation, which pointed out that absorption of G-4 on the surface of phosphorite belonged to physical and chemical types, but the chemical one was in the highest flight. Absorption of amine collector named GE-609 on the surface of quartz belonged to electrostatic and physical type. Distilled water could hardly wash the GE-609 down from the surface of quartz. Leading component of S-721 was the concentrated compound of naphthol sulfonic acid and formaldehyde. The compound had a stronger affinity to the Mg~(2+) on surface of dolomite than the Ca2+ on surface of phosphorite, which is the essential reason in the separation of phosphorite and dolomite. The leading components of soluble glass in function were HSiO3 hydronium and F^SiC^ colloid granule.
通过红外光谱测定以及理论计算的方法研究了选矿药剂与矿物间的作用机理,研究表明:脂肪酸捕收剂G-4对胶磷矿的捕收作用是以化学吸附为主、化学吸附与物理吸附共同作用的结果;胺类阳离子捕收剂GE-609在石英表面的吸附属于静电物理吸附,但很难用水洗的方法使GE-609从石英表面脱附;S-721主要成分为萘酚磺酸与甲醛的缩合物,萘酚磺酸与甲醛的缩合物对白云石表面Mg~(2+)的吸附明显强于对胶磷矿表面Ca~(2+)的吸附,这是胶磷矿与白云石分离的根本原因;水玻璃溶液中对石英起抑制作用的主要组分是HSiO_3~-和H_2SiO_3胶粒,水玻璃除对石英起抑制作用外,对矿浆还具有一定的分散作用。
