文摘

A new HPLC-ICP-MS method was developed for the rapid monitoring of inorganic As. Inorganic As can be analyzed directly since As(III) and As(V) co-eluted. Inorganic As can be separated from all organoarsenic compounds in rice. Three replicates can be analyzed within 6 min. Complete extraction of As species from rice flour was achieved within 15 min.
