【摘 要】針對熱鍍鋅助鍍劑中亞鐵離子對熱鍍鋅產(chǎn)品質(zhì)量的影響及其對在線檢測

的必要性.分析了熱鍍鋅助鍍劑溶液的光譜吸收,并在分光光度分析的基礎(chǔ)上,根據(jù)其

光譜特點(diǎn)自行研制了一種亞鐵離子自動檢測儀.通過微型蠕動泵和該檢測儀實(shí)現(xiàn)了

熱鍍鋅助鍍劑中亞鐵離子的在線檢測.該過程不需要對助鍍劑進(jìn)行其他預(yù)處理,操作

簡便、快速.結(jié)果表明,亞鐵離子濃度在0.1～10 g/L范圍內(nèi),檢測誤差小于0.05 g/L,

吸光度濃度線性方程相關(guān)系數(shù)R=0.999 95.%Becau of the significant effect

of ferrous ion in flux on the quality of hot-dip galvanizing products and

the necessary of the online detection of ferrous ion,the spectral absorption

of the ferrous ion in flux has been investigated in this paper. Bad on

spectrophotometric analysis,the automatic detection equipment for

ferrous ion has been developed according to its special characteristics.

Online measuring of ferrous ion in flux of the hot-dip galvanizing has been

achieved with micropump and the equipment,which is simple,rapid and

does not need pretreatment of the flux. Experimental results show that the

measuring error is less than 0.05 g/L and the linear equation of the

absorption and concentration of the ferrous ion shows a good related

coefficient of 0.999 95(R = 0.999 95) when the ferrous ion concentration is

between 0.1 g/L and 10 g/L in the flux.
