摘要：

The Al constituents of soils and sediments play an important role in the bioavailability and fate of trace heavy metals. Pure Al precipitates rarely exist; instead, Al 3+ is commonly coprecipitated with organics to produce organo–Al hydroxide composites. Herein, we replicate the Al hydroxide organo−mineral composite formation in soils and sediments by synthesizing composites using humic acid (HA) during coprecipitation with Al hydroxide (Al(OH) 3 ). The mineralogy and morphology results indicate the formation of amorphous and nanosized pure A...
