Summary
Home » Science » New Water Treatment Technology Could Fix Mars Soil and Earth SoilUC Riverside engineers have developed a catalyst to remove a dangerous chemical from water on Earth that could also make Martian soil safer for agriculture and help produce oxygen for human Mars explorers.Perchlorate, a negative ion consisting of one chlorine atom bonded to four oxygen atoms, occurs naturally in some soils on Earth, and is especially abundant in Martian soil. Current methods of removing perchlorate from water require either harsh conditions or a multistep enzymatic process to lower the oxidation state of the chlorine element into the harmless chloride ion.Changxu Ren and Jinyong Liu noted anaerobic microbes use molybdenum in their enzymes to reduce perchlorate and harvest energy in oxygen-starved environments.“Previous efforts in constructing a chemical molybdenum catalyst for perchlorate reduction have not been successful,” Liu said.
