Maldonado, S.; Lopez-Vizcaino, R.; Rodrigo, M. A.; Canizares, P.; Navarro, V.; Roa, G.; Barrera, C.; Saez, C. published an article in 2021. The article was titled 《Scale-up of electrokinetic permeable reactive barriers for the removal of organochlorine herbicide from spiked soils》, and you may find the article in Journal of Hazardous Materials.Application of 98-98-6 The information in the text is summarized as follows:
This work aims to shed light on the scale-up a combined electrokinetic soil flushing process (EKSF) with permeable reactive barriers (PRB) for the treatment of soil spiked with clopyralid. To do this, remediation tests at lab (3.45 L), bench (175 L) and pilot (1400 L) scales have been carried out. The PRB selected was made of soil merged with particles of zero valent iron (ZVI) and granular activated carbon (GAC). Results show that PRB-EKSF involved electrokinetic transport and dehalogenation as the main mechanisms, while adsorption on GAC was not as relevant as initially expected. Clopyralid was not detected in the electrolyte wells and only in the pilot scale, significant amounts of clopyralid remained in the soil after 600 h of operation. Picolinic acid was the main dehalogenated product detected in the soil after treatment and mobilized by electro-osmosis, mostly to the cathodic well. The transport of volatile compounds into the atm. was promoted at pilot scale because of the larger soil surface exposed to the atm. and the elec. heating caused by ohmic losses and the larger interelectrode gap. After reading the article, we found that the author used Picolinic acid(cas: 98-98-6Application of 98-98-6)
Picolinic acid(cas: 98-98-6) is used as a chelate for alkaline earth metals. Used to prepare picolinato ligated transition metal complexes. In synthetic organic chemistry, has been used as a substrate in the Mitsunobu reaction and in the Hammick reaction.Application of 98-98-6
