Qhov txawv ntawm ntsuab chemistry thiab ib puag ncig chemistry yog tias ntsuab chemistry yog cov txheej txheem chemical whereas Environmental chemistry yog kev qhuab qhia.
Green chemistry yog kev tswj cov khib nyiab. Tab sis nws suav nrog kev tswj cov khoom pov tseg uas tau tsim thaum lub sijhawm ua haujlwm tshuaj lom neeg. Hauv qhov sib txawv tseem ceeb saum toj no, kev qhuab qhia txhais tau tias "ib ceg ntawm kev paub". Yog li ntawd, ib puag ncig chemistry yog ib ceg ntawm kev paub uas peb tuaj yeem kawm txog tshuaj lom neeg ntawm chemistry. Cov ceg ntawm chemistry no suav nrog kev txheeb xyuas cov kab mob hauv cov xwm txheej thiab kev tsom xam cov av, nrog rau ntau qhov chaw.
Green Chemistry yog dab tsi?
Green chemistry yog cov txheej txheem tshuaj uas peb tswj cov khoom pov tseg uas tsim los ntawm cov txheej txheem tshuaj. Yog li ntawd, nws tag nrho suav nrog kev tu ib puag ncig los ntawm kev tshem cov tshuaj khib nyiab. Peb hu nws chemistry ruaj khov thiab. Qhov peb kawm tshwj xeeb hauv ntsuab chemistry yog siv yam tsawg kawg nkaus ntawm cov tshuaj thaum lub sij hawm cov txheej txheem chemical thiab txo qhov tsim ntawm cov khoom pov tseg.
Daim duab 01: Green Chemistry cuam tshuam txog Kev Txo Cov pa phem ntawm nws qhov chaw
Yog li ntawd, ceg ntawm chemistry no tsom mus rau kev cuam tshuam ib puag ncig ntawm chemistry. Muaj ib txheej txheej txheem uas peb siv nyob rau hauv ntsuab chemistry. Paul Anastas thiab John C. Warner yog cov neeg tsim cov cai no. Muaj 12 lub hauv paus ntsiab lus.
- Kev Tiv Thaiv (kev tiv thaiv pov tseg zoo dua li kev tswj cov khib nyiab)
- Atom kev lag luam (sim txo cov ntaub ntawv cuam tshuam nrog cov txheej txheem tshuaj lom neeg)
- Tsawg cov tshuaj lom neeg muaj kev phom sij (cov txheej txheem tshuaj yuav tsum siv cov tshuaj lom neeg tsawg)
- Tsim cov tshuaj muaj kev nyab xeeb (cov khoom kawg ntawm cov txheej txheem yuav tsum tsis muaj tshuaj lom)
- Cov kuab tshuaj nyab xeeb dua thiab cov pab cuam (peb yuav tsum zam cov tshuaj pab cuam qhov twg los tau)
- Tsim kom muaj zog ua haujlwm (peb lub zog tsawg kawg nkaus rau cov txheej txheem tshuaj)
- Siv cov khoom noj tauj dua tshiab (cov khoom noj tauj dua tshiab tso cai rau nws tsim cov khoom pov tseg tsawg dua)
- Txo cov derivatives (tsawg qhov tsim cov khoom tsis tsim nyog)
- Catalysis (peb tuaj yeem ua cov tshuaj tiv thaiv kom ceev cov txheej txheem)
- Tsim kom degradation (peb tuaj yeem tsim cov khoom lag luam ntawm cov txheej txheem degradable ntau dua)
- Kev tshuaj xyuas lub sijhawm tiag tiag rau kev tiv thaiv kev ua qias tuaj (peb yuav tsum tsim txoj hauv kev tshuaj ntsuam kom tiv thaiv kev ua qias tuaj ntxiv)
- Kev nyab xeeb ntawm chemistry rau kev tiv thaiv kev sib tsoo (xaiv cov ntaub ntawv rau cov txheej txheem uas tsis yog tawg lossis tsis tawg qhov twg los xij)
Environmental Chemistry yog dab tsi?
Environmental chemistry yog ib ceg ntawm chemistry uas peb kawm thiab tshuaj xyuas cov txheej txheem tshuaj uas tshwm sim hauv qhov xwm txheej. Peb hu nws txoj kev qhuab qhia ntawm lub ntsiab ntawm kev paub uas yog qhov tseem ceeb hauv kev txiav txim siab txog qib ntawm cov tshuaj lom neeg. Daim teb no tsuas yog tsom mus rau qhov cuam tshuam ntawm cov tshuaj lom neeg ib puag ncig thiab txo qis ntawm nws los ntawm kev siv cov khoom noj uas tsis yog txuas ntxiv mus rau cov txheej txheem chemical synthesis.
Nyob rau thaj tsam ntawm chemistry, peb kawm txoj hmoo ntawm ib hom tshuaj nyob rau hauv qhov xwm; huab cua, dej thiab av. Nws kuj tseem txiav txim siab txog qhov cuam tshuam ntawm tib neeg kev ua ub no thiab kev ua haujlwm lom neeg ntawm cov tshuaj no. Daim teb no suav nrog ntau pawg xws li dej chemistry (kev sib tham txog dej), av chemistry thiab atmospheric chemistry. Peb kuj kawm txog kev sib kis. Cov kab mob sib kis yog ib yam tshuaj uas peb tuaj yeem pom nyob rau theem siab dua li qhov xav tau (lossis peb ib txwm saib). Cov kab mob paug tuaj yeem tsim los ntawm tib neeg kev ua ub no lossis kev ua ub no lom neeg. Feem ntau cov kab mob yog cov pa phem.
Apart from ntawd, muaj cov cim peb siv los txiav txim qhov zoo ntawm av, dej thiab huab cua. Piv txwv li, peb siv cov kev txwv xws li yaj oxygen (DO qib), BOD qib, COD qib, pH, thiab lwm yam hauv kev txiav txim siab cov dej zoo. Ntxiv mus, cov txheej txheem tshuaj ntsuam xyuas hauv ib puag ncig chemistry tuaj yeem yog qhov zoo lossis ntau.
Qhov txawv ntawm Green Chemistry thiab Environmental Chemistry yog dab tsi?
Green chemistry yog cov txheej txheem tshuaj uas peb tswj cov khoom pov tseg uas tsim los ntawm cov txheej txheem tshuaj. Cov ceg ntawm chemistry no muaj 12 lub hauv paus ntsiab lus tseem ceeb uas peb yuav tsum ua raws li cov txheej txheem chemical synthesis. Ntxiv mus, nws koom nrog txo cov pa phem ntawm nws qhov chaw. Environmental chemistry yog ib ceg ntawm chemistry uas peb kawm thiab txheeb xyuas cov txheej txheem tshuaj uas tshwm sim hauv qhov xwm txheej. Txawm li cas los xij, nws tsis muaj kev cai lossis cov qauv, tab sis nws muaj qhov ntsuas ntsuas qhov zoo ntawm dej, huab cua thiab av. Tsis tas li ntawd, Environmental chemistry tsom rau qhov cuam tshuam ntawm chemistry ntawm ib puag ncig muaj kuab paug. Qhov no yog qhov txawv ntawm ntsuab chemistry thiab ib puag ncig chemistry.
Summary – Green Chemistry vs Environmental Chemistry
Ntsuab chemistry thiab ib puag ncig chemistry yog ob ceg tseem ceeb ntawm chemistry uas cuam tshuam nrog xwm. Qhov txawv ntawm ntsuab chemistry thiab ib puag ncig chemistry yog tias ntsuab chemistry yog cov txheej txheem tshuaj thaum ib puag ncig chemistry yog kev qhuab qhia.
