摘要:收集了1990-2010年中国磷矿石分析技术与方法的中外期刊文献102条,其中单个组分(元素)分析方法
的文献56条,传统的多个组分连测方法的文献24条,现代多元素同时分析方法的文献20条,综合性评述等2
条。20世纪90年代以来,单个组分(元素)测定的方法迅速减少,发表的文献量也大为减少,多元素同时分析技
术得到迅速发展和广泛应用,电感耦合等离子体发射光谱(ICP-AES)和Ⅹ射线荧光光谱(XRF)已成为当今磷
矿石多元素分析的基本的有效的技术方法。ICP-AES用于测定磷矿石中痕量元素(包括稀土元素)具有明显优
势,而磷矿石的主、次量元素分析XRF的测定精度更高,特别是以XRF为主。直接压片制样的XRF技术的“环
境友好”特性使其具有更广的应用前景。结合月前中国磷矿石分析的国家标准分析方法和现有的磷矿石国家
级标准物质,提出了应尽快制订以现代多元素同时分析方法为主的磷矿石分析方法新的国家标准,以与现代主流
分析技术相适应;研制新的具有更多特性量值的磷矿石标准物质,以满足磷矿石资源综合利用研究的需求。

Abstract: A total of 102 published papers from 1990 to 2010 on phosphate ores analysis method in China were
collected which included 56 papers on single element analysis, 24 on traditional continuous measurement analytieal
method of a few components, 20 on modern multi-element analysis simultaneously and 2 reviews. The application of
single element analysis in published papers has declined significantly since the 1990s. Results show that X-ray
fluorescence spectrometry(XR) and inductively coupled plasma spectroscopy(icp-aes are presently the most
effective multi-element analytical methods for measuring phosphate. ICP-AES is good for trace element analysis such as
REES, while XRF is widely applied to major and minor elements analysis. The polyethylene-backed pellets measured b
XRF have broader application prospects because this method does not damage the samples; moreover, there is no
contamination to the environment. According to the current situation of the analysis methods and reference materials of
hosphate ores, it is necessary to formulate a program for simultaneous analysis of multi-elements in order to satisfy the
modern analysis technique. New phosphate ore reference malerials should be developed to meet the requirements of
comprehensive research of phosphate ore resources
Key words phosphate ores; multi-elemcnt analysis; review on literature
