关于磷的野外快速测定的方法很多:有小洞取样——冷溶——液体比色法;有小戥子称样——冷溶——纸条比色法,有小戥子称样——热溶——纸条比色法。我们就上述各方法作了一些对照实验。在此基础上,我们拟定了小洞取样——热溶——液体比色法,并采用标准样品制备色阶。这样,就能基本上控制磷的提取率大致相同,因而适合沉积型和热液型等多矿种,同时采用小洞取样和简化了的操作手续,所以此法又具备快速的特点。
Rapid determination of phosphorus in the field of many ways: a small hole sampling - cold solution - liquid colorimetry; a small prickly heat called - cold-soluble - paper colorimetry, a small prickly heat said - - Hot-melt - paper colorimetry. We made some comparative experiments on the above methods. On this basis, we developed a small hole sampling - hot melt - liquid colorimetric method, and the use of standard sample preparation level. In this way, the phosphorus extraction rate can be basically controlled to be roughly the same, making it suitable for many minerals, such as sedimentary and hydrothermal types, while taking hole sampling and simplifying procedures, so this method possesses rapid characteristics.
