Igcinwe kwindawo yokugcina impahla eyomileyo neyomileyo.
I-2,5-furandicarboxyylic acid (FDCA) kufuneka igcinwe phantsi kweemeko ezigcina uzinzo lwayo kunye nokuthintela ukonakaliswa. Nazi ezinye izikhokelo zokugcina iFDCA:
I-1. Isikhongozeli: Sebenzisa izikhongozeli zomoya ezenziwe ngezinto ze-orgadic, ezinjengeeglasi okanye iiplasitiki ezithile (ezinje ngePolythyene). Qiniseka ukuba isitya sicocekile kwaye somile ngaphambi kokusetyenziswa.
2. Iqondo lobushushu: i-FDCA kwindawo epholileyo neyomileyo. Ngokufanelekileyo, kufuneka igcinwe kubushushu begumbi okanye kwifriji ukunciphisa nawuphi na onesidima.
3. Ukhuseleko lokukhanya: Kulumkele ukuveza i-compound yokukhanya, njengoko ezinye izinto eziphilayo zinovelwano ngokulula. Sebenzisa izikhongozeli zeglasi ye-Amber okanye usongele isikhongozeli nge-aluminium foil ukuya kuthintela ukukhanya.
4. Ulawulo lokufuma: gcina indawo yokugcina yomile ukuthintela ukuthintela ukufunxa, okunokuchaphazela umgangatho we-acid.
5. Ileyibhile: ileyibhile: ilebheli ngokucacileyo kwigama lentonga, uxinzelelo (ukuba luyasebenza), umhla wokugcina, kunye naluphi na ulwazi olufanelekileyo lokhuseleko.
6. Amanyathelo okhuseleko: Landela izikhokelo zoKhuseleko ezifanelekileyo xa ugcina i-FDCA, kubandakanya nokunxiba iigloves kunye neglasi, njengoko kunokubangela ukucaphuka.
7. Ukuchithwa: Xa inkcitho yekhemikhali ayisafuneki, nceda ulahle ngokungqinelana nemigaqo yendawo.
I-2,5-i-furandicarboxyylic acid (FDCA) ithathelwa ingqalelo ukuba inetyhefu esezantsi, kodwa njengemichiza emininzi, inokubeka umngcipheko xa ingalawulwa ngokufanelekileyo. Nazi ezinye zeengcaciso malunga nobungozi bayo emzimbeni womntu:
1. Ukucaphuka: Uqhagamshelwano okanye ukuphefumla kwe-FDCA kunokubangela ukucaphukisa ulusu, amehlo, kunye nephecana lokuphefumla. Kucetyiswa ukuba usebenzise izixhobo zokukhuselwa kobuqu (i-PPE) njengeigloves kunye namagqwirha xa uphatha.
2. Ityhefu: Nangona i-FDCA ingahlelwanga njengetyhefu eyityhefu, ukuveza okanye ukubonakaliswa okugqithisileyo kunokubangela iziphumo ezibi. Iimpawu ezithile zetyhefu zetyhefu azinakumiselwa ngokupheleleyo, ngoko ke kufuneka isetyenziswe ngononophelo.
Iphepha lesi-3. Iphepha ledatha lokhuseleko (i-SDS): Soloko ubhekisa kwi-SDS ye-2,5-firandboxyboxycylicy ye-acid yolwazi oluneengozi kwiingozi zalo, ukuphatha kunye namanyathelo oncedo lokuqala.
I-4. Imeko yolawulo: Nceda ujonge imigaqo yendawo kunye nezikhokelo malunga nokuphatha kunye nokusetyenziswa kwe-FDCA njengoko zinokwahluka ngokomda.
