TRONTIUM takes the same uptake and distribution pathways of Ca within plants; hence disturbs many secondary metabolites. In humans, it can replace Ca in bones and teeth, making them brittle. Thus, remediating Sr-polluted soils has become an obligation to attain a hazard-free environment. In this context, Sr is one of the potentially toxic elements that have received little attention. Thus, the current study aims at investigating the efficiency of using different chelating agents i.e. Na EDTA and DTPA for the chemical extraction of Sr from contaminated soils. To attain this aim, three soil types i.e. a clay loam one and two sandy loam soils varying in their CaCO 3 content were artificially polluted with Sr at three levels (50, 100 and 200 mg Sr kg -1 ); then left to equilibrate for 3 months. Thereafter, Sr was determined within the different soil fractions. In the clayey soil, most Sr was bounded with sesquioxide; followed by the exchangeable fraction, while in the other two soils (sandy loam ones), most of soil-Sr dominated within the exchangeable form, followed by the carbonate bound fraction. The contaminated soils were then subjected to soil leaching via either Na EDTA or DTPA and the extractable amount by both methods were comparable, with slight superiority for DTPA. Generally, the extraction efficiencies of Sr by these chelating agents were low in the sandy loam soils which contained 50 mg Sr kg -1 while increased considerably with increasing the level of soil contamination recording approximately 76-88%. Afterward, fractionation of Sr was accomplished again where the carbonate and organic bound fractions were the dominant ones; yet the exchangeable fraction still represents a substantial percentage. Generally, all fractions prior to soil leaching were correlated with each other. T he two chelating agents were capable of extracting Sr among the different soil fractions except for the sesquioxide bound which was not extractable by Na-EDTA (r 2 =0.371) yet it can be extracted by DTPA (r 2 =0.413). This result provides more evidence for the feasibility of using both EDTA-2Na and DTPA in the chemical extraction of Sr from contaminated soils.
氚在植物体内对钙的吸收和分布途径相同；因此干扰了许多次级代谢产物。在人类中，它可以取代骨骼和牙齿中的钙，使其变脆。因此，修复锶污染土壤已成为实现无危害环境的义务。在这种情况下，锶是一种潜在的有毒元素，很少受到关注。因此，本研究旨在研究使用不同螯合剂（即Na-EDTA和DTPA）从污染土壤中化学提取Sr的效率。为了达到这一目的，对三种土壤类型，即CaCO3含量不同的粘壤土和两种沙壤土，进行了三种水平的Sr人工污染（50、100和200mg Sr kg-1）；然后静置平衡3个月。此后，在不同的土壤组分中测定Sr。在粘性土中，大部分Sr以倍半氧化物为界；其次是可交换部分，而在其他两种土壤（沙壤土）中，大部分土壤Sr以可交换形式为主，其次是碳酸盐结合部分。然后通过Na-EDTA或DTPA对受污染的土壤进行土壤浸出，两种方法的可提取量相当，DTPA稍有优势。一般来说，这些螯合剂对Sr的萃取效率在含有50mg Sr kg-1的沙壤土中较低，而随着土壤污染水平的增加，萃取效率显著提高，约为76～88%。之后，Sr的分馏再次完成，其中碳酸盐和有机结合组分占主导地位；然而可交换部分仍然代表相当大的百分比。一般来说，在土壤浸出之前的所有组分都是相互关联的。这两种螯合剂能够在不同的土壤组分中提取Sr，除了结合的倍半氧化物不能用Na-EDTA提取（r2=0.371），但可以用DTPA提取（r2=0.413）。这一结果为使用EDTA-2Na和DTPA从污染土壤中化学提取Sr的可行性提供了更多的证据。
