摘要：

A　single　alkali　fusion　regent　(Na2O2)　was　used　for　decomposition　of　waste　phosphors　in　this　study.　After　flooding,　alkali　separation,　extraction　by　hydrochloric　acid,　ammonia　separation,　removal　of　silicon　and　rare　earth　oxalate　precipitation,　the　gravimetric　method　was　used　to　determination　of　total　rare　earth　oxide　in　the　waste　phosphors.　Recoveries　and　precision　experiments　were　investigated　in　the　research.　The　measuring　range　of　the　rare　earth　elements　was　10.00%~70.00%　and　the　recovery　at　99.60%~100.40%　was　obtained.　The　method　is　simple,　accurate　and　applicability.　©　2016,　Editorial　Office　of　＂Chinese　Rare　Earths＂.　All　right　reserved.
