Dynamic adsorption thiab regeneration test ntawm electroplating wastewater ntawm electrothermal tube electroplating fibers

Dynamic adsorption thiab regeneration test ntawm electroplating wastewater ntawm electrothermal tube electroplating fibers

Kev npaj ntawm 1.2RPFC fibers

Crosslinking cov tshuaj tiv thaiv: Nyhav ib qho loj ntawm PAN fibers, raug kho ua ntej xws li ntxuav thiab ziab, thiab tom qab ntawd hnov ​​​​mob nrog qee qhov da dej piv ntawm diamine crosslinking tus neeg sawv cev ntawm qhov kub ntawm (110 ± 10) degree, siab ntawm 0. Cov tshuaj tiv thaiv Hydrolysis: Ntxiv cov tshuaj NaOH thiab cov kab sib txuas sib txuas uas tau hais los saum toj no rau 500mL lub raj mis, kaw cov tshuaj tiv thaiv hluav taws xob, kub txog li (100 ± 5) degree hauv lub hwj, hnov ​​​​mob rau 1.5 teev, ntxuav thiab qhuav kom tau RPFC fibers.

1.3 RPFC fiber ntau dynamic adsorption ntawm electroplating dej khib nyiab thiab rov tsim dua tshiab

Dynamic adsorption test: Siv cov dej khib nyiab electroplating los ntawm ib lub Hoobkas electroplating hauv Shenzhen thiab siv atomic emission spectroscopy los txiav txim cov ntsiab lus ntawm Cu2 ntxiv thiab lwm yam hlau ions. Cov liab Ni2 ntxiv rau sab nraud spectrum qhia tau hais tias muaj cov organic tebchaw uas muaj cov pa roj carbon thiab nitrogen hauv cov dej khib nyiab electroplating, nrog tus nqi pH txog li 3. Noj 1.0g RPFC fibers rau hauv lub thawv nws tus kheej, thiab maj mam adsorb. cov electroplating khib nyiab los ntawm cov fibers nyob rau hauv qab-up countercurrent yam ntawm tus nqi ntawm 2-3mL/min nyob rau hauv chav tsev kub kom txog rau thaum cov fibers yog kiag li nkag mus rau hauv, piv txwv li lub peev xwm adsorption mus txog saturation.

1.4 Cov Kev Ntsuas thiab Kev Ntsuas

Cov qauv tshuaj ntsuam xyuas ntawm RPFC fibers tau ua tiav siv ThermoElectron Corporation's IR200 Fourier hloov infrared spectrometer rau cov qauv infrared spectroscopy kuaj. Cov xwm txheej kuaj tau raws li hauv qab no: txoj kev siab KBr phaj; Atomic emission spectroscopy AES-ICP (TJAIRIS ad vantage) tau siv los ntsuas qhov kev hloov pauv ntawm cov hlau ions hauv electroplating cov dej khib nyiab ua ntej thiab tom qab adsorption los ntawm RPFC fibers.
