Pentetic acid or diethylenetriaminepentaacetic acid (DTPA) is an aminopolycarboxylic acid consisting of a diethylenetriamine backbone with five carboxymethyl groups. The molecule can be viewed as an expanded version of EDTA and is used similarly. It is a white solid with limited solubility in water.

BRANDT SEQUESTAR offers a range of high quality, fully chelated EDTA, EDDHA and DTPA micronutrients available in liquid and dry soluble formulations. The chelation shields and protects the nutrients, which prevents them from reacting and …

常用的铁肥有硫酸亚铁、磷酸亚铁铵、硫酸亚铁铵以及人工合成螯合铁如eddha-fe-6、dtpa-fe-11、dtpa-fe-7、edta-fe-13等。 大多数情况下，土施效果并不显著，主要是因为铁会很快转变成难溶性的氧化物。

土壤改良剂：dtpa用作污染土壤的重金属螯合剂，能与土壤中的铁、锰、铜等重金属形成螯合络合物，减少其毒性。 制法： dtpa的合成方法较为复杂，通常通过乙酸酐与乙二胺反应得到二乙基二乙酰胺，再经过甲酸和氯乙酸的反应生成二乙基三胺五乙酸。 安全信息：

2023年1月4日 · EDTA-Fe的化学名称：乙二胺四乙酸铁钠，适用于ph值小于7的土壤，不易被降解。 FeSO4 是传统铁肥在土壤ph值大于7的条件下，基本不被植物吸收，是无机的，不稳定，易被氧化成3价铁。

DTPA (diethylene triamine pentaacetic acid complex) forms a stronger complex with iron than the similar EDTA. The Fe DTPA complex is stable in a pH range of 4-7. More and more, Fe DTPA is seen as the standard source of iron for the fertigation. 20 l can - 200 l barrel - 1000 l multibox.

DTPA Fe is a stable water-soluble metal chelate, used to prevent and correct iron deficiencies.
