Kamar yadda muka sani, nau'ikan polyacrylamide daban-daban suna da nau'ikan maganin najasa daban-daban da kuma tasirinsu daban-daban. Don haka polyacrylamide duk fararen ƙwayoyin cuta ne, ta yaya za a bambanta samfurinsa?
Akwai hanyoyi guda 4 masu sauƙi don bambanta samfurin polyacrylamide:
1. Duk mun san cewa cationic polyacrylamide shine mafi tsada a kasuwa, sai kuma non-ionic polyacrylamide, sannan kuma anionic polyacrylamide. Daga farashin, za mu iya yanke hukunci na farko kan nau'in ion.
2. A narkar da polyacrylamide don auna darajar pH na maganin. Darajar pH da ta dace da samfura daban-daban sun bambanta.
3. Da farko, zaɓi samfuran anionic polyacrylamide da cationic polyacrylamide, sannan a narkar da su daban-daban. A haɗa maganin polyacrylamide don a gwada shi da maganin PAM guda biyu. Idan ya yi aiki da samfurin anionic polyacrylamide, yana nufin cewa Polyacrylamide cationic ne. Idan ya yi aiki da cations, yana tabbatar da cewa samfurin PAM anionic ne ko kuma non-ionic. Rashin kyawun wannan hanyar shine ba zai iya tantance ko samfurin anionic ne ko non-ionic polyacrylamide ba. Amma za mu iya yin hukunci daga lokacin narkewarsu, anions suna narkewa da sauri fiye da non-ions. Gabaɗaya, anion yana narkewa gaba ɗaya cikin awa ɗaya, yayin da non-ion yana ɗaukar sa'o'i ɗaya da rabi.
4. Daga gwaje-gwajen najasa, duk mun san cewa polyacrylamide cationic polyacrylamide PAM ya dace da abubuwan da aka dakatar da su waɗanda ke ɗauke da sinadarai na halitta; anionic PAM ya dace da yawan abubuwan da aka dakatar da su waɗanda ba su da sinadarai na halitta da aka caji da kyau da kuma barbashi da aka dakatar. Ƙimar pH ba ta da sinadarai ko alkaline; polyacrylamide PAM wanda ba ionic ba ya dace da raba abubuwa masu datti a cikin yanayi mai gauraya na halitta da na halitta, kuma maganin yana da acidic ko tsaka tsaki. Fil ɗin da cationic polyacrylamide ya samar suna da girma da yawa, yayin da flocs da anion da non-ion suka samar ƙanana ne kuma sun watse.
