【 摘 要 】

A new layered organic-inorganicmaterial based on 𝜆-Zirconium phosphate (𝜆-ZrP) and ethylenediaminetetraacetic acid (H4Y) has been prepared. The thermal analyses, X-ray diffractometry and FT-IR spectrophotometry confirm the introduction of H4Y inside the interlayer gallery of 𝜆-ZrP. The pristine 𝜆-ZrP and its new polyaminocarboxylic acid functionalized derivative (𝜆-ZrPH2Y) exhibit high potential for the application in the area of hard water treatment, where their Ca2+ uptake capacities are found to be 32.0 and 40.4mg Ca2+ per gram of 𝜆-solid, respectively.
