氧化反應(yīng)電位(又稱ORP)是物質(zhì)氧化或還原性質(zhì)的一種表示. 標(biāo)準(zhǔn)狀態(tài)下, 用可接受或釋放電子的金屬電極,即可測定該值。金屬電極可以使用鉑或金(Pt或Au)。電極材料必須是不與待測物質(zhì)發(fā)生反應(yīng)的惰性金屬。如果水溶液中含有氧化劑或還原劑, 那末電子就進(jìn)行交換。在酸/堿反應(yīng)中是氫離子H+的交換, 而在其它化學(xué)反應(yīng)中是電子的交換。
上述過程簡稱還原和氧化, 即氧化和還原反應(yīng), 氧化還原對于凈化時(shí)去除 鉻酸鹽, 亞硝酸鹽非常重要。凡是能釋放一個(gè)或多個(gè)電子的物質(zhì)稱之為還原劑, 獲得電子的是氧化劑。因此在還原反應(yīng)中電子數(shù)目增加, 在氧化反應(yīng)中電子數(shù)目減少。
引進(jìn)先進(jìn)的技術(shù)與采用進(jìn)口元器件,極大地縮小了體積,降低了成本,保持原有的優(yōu)良品質(zhì),使O.R.P的使用得到了普及。適用于具有負(fù)電位的功能性能量凈水機(jī)和能量水杯及其它需求的負(fù)電位值測定之用。

也可以根據(jù)您的需要進(jìn)行配置
水質(zhì)檢測工具箱:適用于凈水產(chǎn)品銷售人員,售后服務(wù)人員,凈水產(chǎn)品專賣店,商場凈水產(chǎn)品專柜,凈水企業(yè)及水處理工廠,養(yǎng)殖業(yè)及有需要做水質(zhì)測試的單位企業(yè)等.
本品是有由多種有機(jī)化學(xué)物及多種助劑復(fù)合而成的具有強(qiáng)氧化劑的高科技產(chǎn)品,外觀白色略帶黃色粉末。它不僅可以打破螯合劑對金屬離子的配位鍵,而且能打破有機(jī)分子本身的C-C、C-O、C-N及C-S等鍵,還能破壞CN化物。該藥劑加入污水中,破解有機(jī)物生成CO2和H2O,對環(huán)境不會造成二次污染,屬綠色環(huán)保型水處理劑。
產(chǎn)品特性:
1.藥劑用量少,反應(yīng)速快; 2.效果好,處理費(fèi)用較低。
使用領(lǐng)域:
電鍍行業(yè)廢水 金屬制品制造行業(yè)廢水
表面處理行業(yè)廢水 電子零件制造行業(yè)廢水
印制電路板(PCB)行業(yè)廢水 鋼鐵、制鐵行業(yè)廢水
