Rau qee cov ntaub ntawv, sulfuric acid yog ntxiv ua ntej cua sov los pab txhawb kev puas tsuaj ntawm cov organic teeb meem thiab kho qee cov hlau raws li lawv cov sulfate ntsev kom tiv thaiv tsis muaj zog. Thaum siv sulfuric acid, cov khoom tshwm sim yog hu ua sulfated tshauv.
Lub hom phiaj ntawm sulphated tshauv yog dab tsi?
Kev ntsuas cov hmoov tshauv sulfated siv cov txheej txheem los ntsuas tus nqi ntawm cov khoom seem uas tsis tau hloov pauv los ntawm cov qauv thaum cov qauv raug ignited nyob rau hauv lub xub ntiag ntawm sulfuric acid. Qhov kev ntsuam xyuas feem ntau yog siv rau kev txiav txim siab cov ntsiab lus ntawm inorganic impurities hauv cov organic tshuaj
Dab tsi yog qhov txawv ntawm sulphated tshauv thiab ROI?
Tsis muaj qhov sib txawv ntawm qhov txheej txheem, ob qho tib si tib yam. Peb feem ntau hais nws li SULPHATED ASH TEST / ROI. IN INDIAN PHARMACOEPIA, hu nws li ROI thiab hauv USP, hu nws ua SULPHATED ASH TESH. Ob leeg yog siv los txiav txim siab txog cov ntsiab lus ntawm INORGANIC teeb meem hauv ib qho khoom siv organic.
Kuv yuav txo cov seem hauv kuv qhov hluav taws xob li cas?
Heat, maj mam thaum xub thawj, ntawm qhov kub thiab txias raws li qhov ua tau kom txog thaum cov khoom ua kom huv si, txias, ces tshwj tsis yog txwv tsis pub coj mus rau hauv tus kheej monograph, moisten cov seem nrog ib qho me me (feem ntau 1 ml) ntawm sulfuric acid.
Vim li cas purity thiaj txiav txim siab hauv cov hmoov tshauv?
Sulphated ash test yog siv los txiav txim siab Organic purity thaum cov organic tshuaj tsis muaj solubility hauv cov kuab tshuaj kom paub tias nws yog purity. Yog, Txhua txoj kev tshauv (qhuav, ntub thiab tsis kub plasma) muaj kev txhawj xeeb nrog kev kawm purity ntawm tus qauv.
