鈉吸附比 的英文怎麼說
中文拼音 [nàxībùbǐ]
鈉吸附比
英文
sodium adsorption ratio-
The effective regeneration procedure is soaking the adsorbent 30 ~ 50h with 1 - 2 % al2 ( so4 ) 3 for activated alumina and 20 ~ 30h with 1 - 1. 5 % naoh for bone char. studies show both activated alumina and bone char are excellent adsorbents for the removal of fluoride from drinking water. fluoride concentration below 1. 0mg / l can be acquired easily with them and meets the requirement of drinking water standards
對兩種除氟劑進行的再生液與吸附劑體積比為1 : 1的再生實驗表明:用硫酸鋁溶液對活性氧化鋁再生,再生濃度為1 2 ,再生時間為30 50h ,沖洗浸泡時間為5h效果較好;對骨炭再生,氫氧化鈉再生液濃度為1 1 . 5 ,再生時間為20 30h效果較好。When nals was used as the collector in the process, the optimal conditions were the ph of feed solution 5. 0 - 6. 0, air flow rate 100ml / min, the liquid column depths 20cm, the surfactant concentration determined by its cmc and feed concentration. under this condition, the 3 can be above 20. also, the optimal ph ( 5. 0 ) was calculated theoretically for the recovery of the cu ( ii )
對以十二烷基硫酸鈉為捕集劑的泡沫吸附分離過程的工藝參數進行了研究,並得出本分離系統所確定的最佳工藝參數為: ph5 . 0 6 . 0 ,氣體流量100ml min ,液位高度20cm ,最佳表面活性劑濃度由其臨界膠束濃度和原料液濃度確定,此時(濃縮比)可達20以上;同時還從理論上推算出泡沫吸附分離銅的最佳ph值范圍為5 . 0左右。An additional problem related to precipitation of calcium is that the sodium hazard of the water itself is increased by virtue of increasing the sodium adsorption ratio ( sar )
與鈣沉澱相關的另一個問題是鈉吸附比( sar )的增加造成水本身的鈉害加重。
