Phosphorites from the Yichang, Haikou and Baokang areas were used for remediation of aqueous cadmium (Ⅱ) ion. The experimental results showed that in the condition of pH=6, action time=15 min, initial Cd concentration=30 mg/L, the cadmium (Ⅱ) attenuation by Yichang siliceous phosphorite is 98% and attenuated Cd is 4.5 mg/g (sample). The respective numbers for Baokang calcareous phosphorites are much lower, and those for Haikou phosphorites are intermediate. Owing to the differences in sorption mechanism,...

Phosphorites from the Yichang, Haikou and Baokang areas were used for remediation of aqueous cadmium (Ⅱ) ion. The experimental results showed that in the condition of pH=6, action time=15 min, initial Cd concentration=30 mg/L, the cadmium (Ⅱ) attenuation by Yichang siliceous phosphorite is 98% and attenuated Cd is 4.5 mg/g (sample). The respective numbers for Baokang calcareous phosphorites are much lower, and those for Haikou phosphorites are intermediate. Owing to the differences in sorption mechanism, the properties for cadmium remediation by phosphorite are different from those for lead remediation.

用宜昌、海口、保康等地磷块岩对水溶液中镉离子的吸附实验结果表明 ,影响吸附效果的主要因素有介质的酸度 ,作用时间 ,初始Cd2 +浓度和样品用量。在 pH =6,作用时间为 15min ,初始Cd2 +浓度为 3 0mg/L的实验条件下 ,宜昌硅质磷块岩对镉离子的去除率可达 98% ,去除容量为 4 .5mg/ g(样品 ) ,吸附效果最好 ,海口的效果次之 ,而保康钙质磷块岩的效果最差。上述差异可能与这些磷块岩的矿物成分和结晶化学特性之间的差异有关。

The phosphorites of Gezhongwu Formation in Zhijin county mainly consist of bioclast dolomitic and siliceous phosphorite. They generally show bioclast structure and are mainly made of small shelly fossils and alga fossils. The REE contents of phosphorites are analyzed by Finnigan Mat Element high resolution ICP-MS. The results of analysis suggest that the phosphorites are rich in REE, especially in Y element and the total REE concentrations are high. The Zhijin phosphorites show a record of the negative...

The phosphorites of Gezhongwu Formation in Zhijin county mainly consist of bioclast dolomitic and siliceous phosphorite. They generally show bioclast structure and are mainly made of small shelly fossils and alga fossils. The REE contents of phosphorites are analyzed by Finnigan Mat Element high resolution ICP-MS. The results of analysis suggest that the phosphorites are rich in REE, especially in Y element and the total REE concentrations are high. The Zhijin phosphorites show a record of the negative Ce anomalies,which indicate an oxidzing marine depositional conditions.PAAS normalized REE concentrations plotted against respective atomic numbers are chatacterized by slight enrichment of MREE,forming the hat-shaped REE patterns.The patterns suggest that fauna played an important role in the phosphorite formation.The phosphorite characters of positive Eu anomaly,the high ΣREE and the high ratio of ΣLREE and ΣHREE suggest that Zhijin phosphorites belong to the normal marine deposition associated with hydrothermal activity.

 贵州织金戈仲伍剖面戈仲伍组磷质岩主要为生物碎屑白云质、硅质磷块岩,普遍形成生物碎屑结构,以小壳类动物化石及藻类化石为主。采用电感耦合等离子体-质谱仪(ICP-MS)对戈仲伍组磷质岩样品的稀土元素含量进行测定分析,结果表明:磷质岩中普遍富集稀土元素,含稀土总量ΣREE较高,尤其富集Y重稀土元素;磷质岩具Ce负异常,指示环境处于氧化程度相对较高状态;稀土元素北美页岩标准化模式曲线为帽状形态,指示在磷质岩形成过程中有生物或有机质参与作用;磷质岩普遍具Eu正异常、稀土总量较高、ΣLREE/ΣHREE比值较高的特征,暗示戈仲伍组磷矿具有正常海相沉积伴有海相热水沉积混合成因的特征。

采用电感耦合等离子体-质谱仪(ICP-MS)对贵州织金戈仲伍剖面戈仲伍组磷矿岩样品的微量、稀土元素含量进行了测定。戈仲伍组磷矿岩主要为生物碎屑白云岩、硅质磷块岩,普遍形成生物碎屑结构,以小壳类动物化石及藻类化石为主。分析结果表明,磷矿岩中As、Sb等微量元素富集,Co/Ni的比值为0.14,明显小于1;U/Th比值介于1.27~7.39之间,平均值为3.40;在lgw(U)-lgw(Th)关系图、Cr-Zr的关系图中样品点几乎都落在热水沉积区,表现出热水沉积成因的地球化学特征。磷矿岩中普遍富集稀土元素,含稀土总量∑REE较高,尤其富集Y重稀土元素;磷矿岩具Ce负异常,指示环境处于氧化程度相对较高状态;稀土元素北美页岩标准化模式曲线为帽状形态,指示在磷矿岩形成过程中有生物或有机质参与作用;磷矿岩普遍具Eu正异常、稀土总量较高、∑LREE/∑HREE比值较高的特征,暗示戈仲伍组磷矿岩具有正常海相沉积伴有海相热水沉积混合成因的特征。
