A new spectrophotometric method for the determination of chromium has been developed. In HCl medium, the chromium oxidizes hydroxylammonium chloride to form nitrite, which produces a pink azo dye when reacting with p-aminobenzene sulfonic acid and α-naphthylamine.

基于铬在稀盐酸介质中氧化盐酸羟胺产生亚硝酸根，而亚硝酸根与对氨基苯磺酸重氮化后可与α-萘胺偶联产生粉红色偶氮染料，提出了分光光度法测定铬的新方法。

In HCl medium, iodate oxidizes hydroxylammonium chloride to form nitrite, which can produce a red azo dye with the reaction of p nitroaniline and α naphthylamine.

基于碘酸根在稀盐酸介质中氧化盐酸羟胺产生亚硝酸根，而亚硝酸根和对硝基苯胺重氮化后可以与α-萘胺偶联产生红色偶氮染料，提出了分光光度法测定碘的新方法。

Sodium nitrite was strongly adsorbed by the dreg and DF from the white trumpet lily and tiger lily.

麝香百合渣及其膳食纤维和卷丹膳食纤维吸附亚硝酸钠实验结果表明：pH2时，这些样品都对亚硝酸根离子有较强的吸附作用，吸附率分别为73.8％、88.5％、80.2％。

First use soap-free emulsion preparation for polystyrene spheres, and the kernel, Reuse are silicon acetic tetraethyl ortho-silicate in ammonia catalytic hydrolysis, formed under the condition of silica, charged by six water or their cerium, six of methylene amine solution HMT (4) into the negatively charged, uniform cerium oxide coated surfaces to PS microspheres, core-shell structure of PS - CeO2 and PS - SiO2 composite microspheres.
