HMA-2000系列重金屬(shu)在(zai)(zai)線分析儀(yi)采(cai)用(yong)陽極(ji)(ji)(ji)溶出(chu)伏(fu)安法檢(jian)測(ce)原理。經(jing)預處理的(de)水(shui)樣在(zai)(zai)高(gao)溫(wen)高(gao)壓消解后，與(yu)電(dian)(dian)(dian)(dian)解液(ye)在(zai)(zai)檢(jian)測(ce)池內混(hun)合，然后在(zai)(zai)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)施(shi)加一還原電(dian)(dian)(dian)(dian)勢(shi)將混(hun)合液(ye)中(zhong)的(de)待測(ce)金屬(shu)離子富集在(zai)(zai)工作電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，再按階梯脈(mo)沖方(fang)式(shi)持續(xu)改(gai)變外加電(dian)(dian)(dian)(dian)勢(shi)，使富集在(zai)(zai)工作電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)金屬(shu)元素溶出(chu)，并(bing)檢(jian)測(ce)溶出(chu)時的(de)電(dian)(dian)(dian)(dian)流信(xin)號強度(du)，根據溶出(chu)電(dian)(dian)(dian)(dian)流信(xin)號峰(feng)強度(du)換算得到被測(ce)組分的(de)濃度(du)。
HMA-2000系(xi)列重金(jin)屬(shu)在線分析(xi)儀(yi)采用陽極(ji)溶出伏安法檢(jian)測(ce)原理(li)。經預處理(li)的水樣在高(gao)溫高(gao)壓消解后，與電(dian)(dian)(dian)(dian)解液在檢(jian)測(ce)池(chi)內(nei)混(hun)合，然后在電(dian)(dian)(dian)(dian)極(ji)上(shang)施加(jia)一(yi)還原電(dian)(dian)(dian)(dian)勢將混(hun)合液中的待測(ce)金(jin)屬(shu)離子富集在工作電(dian)(dian)(dian)(dian)極(ji)上(shang)，再按階梯脈沖(chong)方式持續(xu)改變(bian)外加(jia)電(dian)(dian)(dian)(dian)勢，使富集在工作電(dian)(dian)(dian)(dian)極(ji)上(shang)的金(jin)屬(shu)元(yuan)素溶出，并檢(jian)測(ce)溶出時(shi)的電(dian)(dian)(dian)(dian)流(liu)信號強(qiang)度，根據溶出電(dian)(dian)(dian)(dian)流(liu)信號峰強(qiang)度換算得到(dao)被測(ce)組分的濃(nong)度。
