本世纪五十年代中期重新发现了交换性铝,那时,对交换性铝的认识是简单的和一致的,但现在情况已不同了。当然,因为进行了更多的研究我们才逐步知道了一点铝在土壤中的行为,例如聚合物的形成、带羟基铝粘土矿物的层间化以及铅与土壤有机质的相互作用。今天看来,交换性铝的概念仍具有重大的现实意义,但是,它包括的只是土壤中铝的多种存在形式之一。本文讨论了自五十年代以来有关铝的研究结果,并加以评述。 The exchange of aluminum was rediscovered in the mid-1950s when the understanding of exchangeable aluminum was straightforward and unanimous, but things are different now. Of course, as more studies are conducted, we have come to know a little about the behavior of aluminum in soils, such as the formation of polymers, interlamination of hydroxy aluminum-bearing clay minerals, and the interaction of lead with soil organic matter. Today, the concept of exchangeable aluminum is still of great practical significance, but it includes only one of the many forms of aluminum in the soil. This article discusses and reviews the findings of the research on aluminum since the 1950s.
