Kuv puas tuaj yeem mus xyuas koj lub tuam txhab thiab lub Hoobkas hauv Suav teb?

Tseeb. Koj zoo siab tos txais koj tuaj xyuas peb lub tuam txhab hauv Zibo, Suav teb. (1.5H tsav tsheb los ntawm Jinan)

Kuv tuaj yeem tso qhov kev txiav txim li cas?

Koj tsuas yog xa peb cov lus nug rau ib tus neeg sawv cev muag khoom kom tau txais cov ntaub ntawv qhia txog kev txiav txim, thiab peb yuav piav qhia cov txheej txheem kom ntxaws. Tsis tas li ntawd, muaj lwm txoj hauv kev tsim cov oxalic acid:
(1) Txoj kev npaj cov pa roj carbon dioxide: Cov pa roj carbon dioxide raug txo qis ua ntej rau CO2 nruab nrab thiab tom qab ntawd hloov mus rau lwm cov khoom siv organic. Oxalic acid tau txais los ntawm kev siv ntau yam pa roj carbon dioxide nrog cov txheej txheem electrochemical thiab γ-rays, tshav ntuj, lossis cov teeb mercury siab.
(2) Txoj kev yaj alkali siv cov khoom nplua nuj cellulose: Kev sib xyaw ntawm cov khoom nplua nuj cellulose (xws li ntoo pov tseg, chaff, thiab lwm yam) thiab inorganic muaj zog alkali yog co-yaj ntawm 513–558 K los tsim ntau dua 50% oxalate. Cov oxalate siv lead ua los ntawm crystallization, thiab tom qab ntawd sulfuric acid siv los tau txais cov oxalic acid tiav. Txoj kev no muaj cov txheej txheem yooj yim rau kev npaj oxalic acid, tab sis tus nqi hloov pauv ib zaug yog qis (tsawg dua 35%), kev siv alkali siab, thiab kev ua qias tuaj ib puag ncig yog hnyav.
(3) Txoj kev tsim cov khoom siv raw thee: Npaj los ntawm ntau yam peats ua cov khoom siv raw. Piv txwv li, oxalic acid yog tsim los ntawm peat ntawm genera Sphagnum thiab Polytrichum los ntawm nitric acid oxidation. Cov tshuaj tiv thaiv yog nqa tawm ntawm 343 K rau 8-9 teev, nrog rau cov txiaj ntsig txog li 95%. Thaum cov khoom siv raw xws li thee tar siv los tsim oxalic acid, cov txiaj ntsig kuj ncav cuag 51%.
