Qhov sib txawv tseem ceeb ntawm ionic mobility thiab ionic tshaj tawm yog tias ionic mobility txhais lub peev xwm ntawm ions txav mus los ntawm qhov nruab nrab whereas ionic tshaj tawm txhais tias cov ions txav nrawm npaum li cas los ntawm nruab nrab.
Kev coj ntawm electrolyte tshwm sim los ntawm kev txav ntawm ions los ntawm qhov nruab nrab electrolytic. Txawm li cas los xij, lawv tsis txav mus rau qhov kev txiav txim zoo. Yog li ntawd, qhov nrawm ntawm qhov kev txav no txawv ntawm ib qho ion mus rau lwm qhov. Qhov kev txav ntawm ions yog vim muaj kev siv hluav taws xob sab nraud.
Ionic Mobility yog dab tsi?
Ionic kev txav mus los lossis hluav taws xob txav yog lub peev xwm ntawm ions txav mus los ntawm qhov nruab nrab ntawm qhov cuam tshuam ntawm hluav taws xob. Ions yog them cov khoom; Yog li, lawv muaj qhov tsis zoo lossis qhov zoo ntawm hluav taws xob. Yog li ntawd, ib qho hluav taws xob tuaj yeem cuam tshuam qhov kev txav ntawm cov ions no. Peb lub npe txheej txheem ntawm kev sib cais ions raws li lawv qhov kev txav mus los hauv theem roj li "ion mobility spectrometry". Ntxiv mus, yog tias peb ua qhov kev sib cais ntawm cov kua theem, peb hu nws "electrophoresis".
Daim duab 1: Ion Mobility Spectrometry
Tsis tas li ntawd, hauv kev ua lej, peb tuaj yeem txhais qhov kev txav mus los ntawm ionic raws li qhov piv ntawm qhov nrawm nrawm mus rau qhov loj ntawm qhov hluav taws xob. Nws yog raws li nram no:
μ=vd/E
μ yog ionic mobility thaum Vd yog qhov nrawm nrawm ntawm ion thiab E yog qhov loj ntawm qhov siv hluav taws xob. Qhov kev sib npaug no siv tau rau theem roj lossis theem kua. Txawm li cas los xij, qhov hluav taws xob yuav tsum zoo ib yam thoob plaws hauv nruab nrab.
Ionic Velocity yog dab tsi?
Ionic tshaj tawm yog qhov nrawm tau los ntawm ion txav mus los ntawm qhov nruab nrab hauv qab chav tsev hluav taws xob. Peb lub npe nws yog drift tshaj tawm, thiab nws yog tus nqi nruab nrab. Ntawm no, lub teb hluav taws xob yuav tsum tsis sib xws, thiab nws tuaj yeem siv lub zog ntawm cov khoom txav mus los. Ntxiv mus, peb tuaj yeem muab qhov ionic tshaj tawm raws li hauv qab no:
Vd=μE
Vd yog ionic tshaj tawm, thiab μ yog ionic mobility thaum E yog qhov loj ntawm qhov hluav taws xob sab nraud. Chav ntsuas ntawm qhov ntsuas no yog ms-1.
Qhov txawv ntawm Ionic Mobility thiab Ionic Velocity yog dab tsi?
Ionic kev txav mus los thiab kev tshaj tawm ionic yog cov ntsiab lus tshuaj lom neeg heev. Qhov sib txawv tseem ceeb ntawm ionic mobility thiab ionic tshaj tawm yog tias ionic mobility txhais tau tias muaj peev xwm ntawm ions txav mus los ntawm qhov nruab nrab thaum ionic tshaj tawm txhais tau tias cov ions txav mus los ntawm qhov nruab nrab. Ntxiv mus, lwm qhov sib txawv tseem ceeb ntawm ionic mobility thiab ionic tshaj tawm yog qhov ntsuas ntawm ionic mobility yog m2V−1 s. −1 thaum chav ntsuas ntawm ionic tshaj tawm yog ms−1
Summary – Ionic Mobility vs Ionic Velocity
Ions yog them cov khoom. Muaj ob hom loj xws li cations thiab anions. Txawm li cas los xij, ob qho tib si ions tuaj yeem ua rau muaj kev cuam tshuam ntawm electrolyte. Nyob rau hauv luv luv, ionic mobility thiab ionic tshaj tawm yog ob lub tswv yim tshuaj uas piav qhia txog kev txav ntawm cov ions los ntawm qhov nruab nrab. Qhov sib txawv tseem ceeb ntawm ionic mobility thiab ionic tshaj tawm yog tias ionic mobility txhais tau tias muaj peev xwm ntawm ions txav mus los ntawm qhov nruab nrab thaum ionic tshaj tawm txhais tau tias cov ions txav mus los ntawm nruab nrab.
