MnPO4合成疑问?Journal of Alloys and Compounds 454 (2008) 78–82Serrabancaite, MnPO4·H2O compound was prepared by solution precipitationmethod using Mn(NO3)2·4H2O ( 99% purity, Fluka) and phosphoric acid86.4%, w/w H3PO4, Merck) as starting materials and water–ethanol as baseagent. Five grams of Mn(NO3)2·4H2O was dissolved in 5mL of 70% H3PO4and then 20mL of ethanol was added. The resulting solution was vigorouslystirred for 2 h at 40 ?C and finally the gray-green precipitates were obtained.This process can be explained by the following reaction:Mn(NO3)2 · 4H2O(aq) + H3PO4(aq)→MnPO4 · H2O(s) + 2NO3? + 3H+ + 3H2O这种方 法能 合成MnPO4吗?二价锰怎么转化成三价锰?查看更多2个回答 . 1人已关注
