Aplicação

  • Grafting nanocellulose with diethylenetriaminepentaacetic acid: Development of a novel paper additive for enhancing recycled OCC pulp fibers by functionalizing nanocellulose with DTPA (Li et al., 2022).
  • Controlling multivalency and multimodality: Study on up to pentamodal dendritic platforms based on DTPA cores, illustrating DTPA′s role in multivalency and drug delivery systems (Pulido et al., 2014).
  • Adsorption of Hg (II) ions by DTPA-modified cellulose: Exploration of a DTPA-modified cellulose adsorbent for removing mercury ions from aqueous solutions (Li et al., 2019).
  • DTPA-functionalized multi-walled carbon nanotubes/titanium oxide-PVDF nanofiber membrane: Study on the effective separation of oil/water mixtures using a DTPA-functionalized membrane (Venkatesh et al., 2021).
