Abstract Phosphate minerals derive from marine sedimentary rocks and can be used as soil and water remediation agents. Phosphate deposits are abundant in Morocco. These rocks have important surface properties allowing a good retention of heavy metals (Pb2+, Cd2+, Cu2+, Zn2+, Cr3+, Cr6+) and organic micropollutants (phenol, pyridine, dyes and drugs), which has been well described herein. A retention mechanism model has also been proposed. Organic micropollutants can bind to the phosphate mineral surfaces but at different rates, depending on their chemical composition, whose mechanism is related to the nature of Van Der Waals interactions and hydrogen bonds between different molecules. These experimental results show that phosphate minerals can be as an excellent natural agent used for remediation of contaminated soils and industrial effluents.

天然磷酸盐在去除水中重金属和有毒有机物方面的表征和评估

摘要 磷酸盐矿物来源于海相沉积岩，可用作土壤和水体修复剂。摩洛哥的磷酸盐矿藏丰富。这些岩石具有重要的表面特性，可以很好地保留重金属（Pb2+、Cd2+、Cu2+、Zn2+、Cr3+、Cr6+）和有机微污染物（苯酚、吡啶、染料和药物），本文对此进行了详细描述。还提出了保留机制模型。有机微污染物可以与磷酸盐矿物表面结合，但结合速率不同，这取决于它们的化学成分，其机制与范德华相互作用和不同分子之间的氢键的性质有关。这些实验结果表明，磷酸盐矿物可以作为一种优良的天然药剂用于污染土壤和工业废水的修复。
