| 摘 要： | Ｐｔ，Ｐｄ，Ｒｈ，Ａｕ能溶于王水及盐酸加双氧水中，而Ｒｈ溶于热硫酸或浓盐酸加氯酸钙，试验中可用王水溶矿，在王水或盐酸介质和氯化亚锡存在下用负载二苯基硫脲的混合碳粉富集痕量的Ｐｔ（Ⅱ）、Ｐｄ（Ⅱ），Ｒｈ（Ⅰ），Ａｕ（Ⅱ）络合物，吸附载体灰化后用发光谱测定，测定灵敏度达到了１×１０＾－９。 |
| 关 键 词： | 痕量贵金属 发射光谱法 二苯基硫脲 |

| Abstract: | Pt,Pd,Rh,Au can be dissolved in aqua regia and hydrochloric acid added with hydrogen peroxide.In Experiment,we use the minerals which dissolved in aqua regia.The trace Pt() Pd() Rh() and Au() were loaded by the mixed carbon powder which carried diphenyl thiourea when aqua regia or hydrochloric acid and stannous chlorids as media are present.Loader adsorbed precious metals was ashed and determined with atomic emission spectrometry.The absolute sensitivity of Pt,Pd,Rh and Au are 0.0110-6.The determination sensitivity counted with 10 grams of samples is 110-9. |
| Keywords: | Trace Precious Metals Atomic Emission Spectrometry Diphenyl Thiourea |
