The method based on microliter sample dilution was applied to monitoring of ammonium nitrogen in fermentation solutions. 把微升進(jìn)樣在線(xiàn)稀釋技術(shù)同氣體擴散光度法結合，測定了農藥發(fā)酵液中氨態(tài)氮的含量。
The key pollution indicators are ammonia nitrogen and BOD. 主要污染指標是氨氮和生化需氧量。
The performances of different powdered zeolites for removing low-concentration ammonia nitrogen from water were compared through batch experiments. 通過(guò)靜態(tài)試驗比較了不同產(chǎn)地粉末狀沸石去除水中低濃度氨氮的性能。
