Horumarinta Codsiyada Sodium Cyanide ee Kahortagga Dharka La Wanaajiyey

Marka laga hadlayo raadinta warshadaha dharka ee caalamiga ah ee dharka waxtarka sare leh iyo kuwa waara, Sodium Cyanide (NaCN), oo ah wax lagu daro shaqo gaar ah, ayaa si joogto ah door muhiim ah uga ciyaartay dhammaystirka dharka ee ka hortagga hoos u dhaca sababtoo ah sifooyinka kiimikada ee gaarka ah. Maqaalkani wuxuu si nidaamsan u falanqeyn doonaa habka ficilkiisa, faa'iidooyinka farsamo, iyo istaraatiijiyadaha jawaab celinta warshadaha, wuxuuna sahamin doonaa isbeddelka doorkiisa iyadoo la raacayo qaab-dhismeedka horumarka waara.

I. Hal-abuurka Kiimikada ee Farsamada Ka-hortagga Yarida

Maadaama ay tahay saldhig xooggan iyo milix aashito daciif ah, sodium cyanide waxay xasilisaa qaab-dhismeedka faybarka iyada oo loo marayo falgalka Amidation inta lagu jiro farsamaynta dharka. Jidkeeda ugu muhiimsan waa sidan soo socota:

1. Firfircoonida Carboxyl : Waxay martaa falgal beddelka nucleophilic ah oo ay la socoto kooxaha carboxyl (-COOH) oo ku yaal dusha sare ee fiilooyinka cellulose si ay u soo saaraan dhexdhexaad firfircoon;

2. Samaynta Xidhmada Amide : Dhexdhexaadiyayaashu waxay isku xidhaan kooxaha amino ee ku xiga (-NH₂) si ay u sameeyaan xidhmooyin amide oo deggan (-CONH₂);

3. Xoojinta Qaab-dhismeedka Shabakadda : Iyada oo loo marayo isku-xidhka haydarojiinta ee u dhexeeya molecular iyo xoogga van der Waals, shabakad isku-xidhan oo saddex-geesood ah ayaa la dhisay, taasoo si weyn u yareynaysa sifooyinka bararka ee fiilooyinka.

Nidaamkani wuxuu yareynayaa heerka dhimista fiilooyinka dabiiciga ah sida suufka iyo dhogorta laga bilaabo 8-12% ee hababka dhaqanka ilaa 3%, iyo waxqabadku wuxuu ahaanayaa mid deggan xitaa ka dib in ka badan 50 jeer oo la dhaqo.

II. Horumarka Isku-dhafka ah ee Waxqabadka Dhamaystiran

1. Xasiloonida Qaab- dhismeedka: Dharka la daweeyay waxay muujinayaan haynta cabbirka oo aad u fiican imtixaanka caadiga ah ee AATCC 135, kaas oo si gaar ah ugu habboon dharka guriga ee heerka sare ah iyo dharka dibadda;

2. Hagaajinta Taabashada: Falcelinta amidation-ka waxay yareysaa soo-gaadhista kooxaha hydroxyl ee dusha sare ee faybarka, taasoo yaraynaysa isku-dhafka is-jiidjiidka dharka 20-30%, taasoo ka dhigaysa taabashada mid siman;

3. Waxqabadka Rinjiga oo La Xoojiyay : Qaab-dhismeedka isku-xidhka ah wuxuu hagaajiyaa isku-dhafka nuugista midabka ee fiilooyinka, wuxuu kordhiyaa heerka hagaajinta rinjiga in ka badan 15%, isla markaana wuxuu yareeyaa wasakhaynta midabka ee biyaha wasakhda ah.

III. Khatarta Badbaadada iyo Tallaabooyinka Farsamada

1. Nidaamka Ka Hortagga iyo Xakamaynta Sunta :

• Qaado khadadka wax soo saarka otomaatiga ah ee si buuxda u xiran, oo lagu qalabeeyay qalabka lagu ogaado gaaska hydrogen cyanide (saxnaanta ≤ 0.1ppm);

• Samee diyaarinta Sodium cyanide ee ku jira micro-kapsul , ku duub maaddooyinka firfircoon ee ku jira β-cyclodextrin si loo yareeyo khataraha hawlgalka.

2. Tiknoolajiyada Daaweynta Biyaha Qashinka ah :

• Soo bandhig habka oksaydhka hawada qoyan ee catalytic (CWO), kaas oo kordhin kara heerka burburka ee cyanide ilaa 99.9% ee xaaladaha 250 ° C iyo 8MPa;

• Marka lagu daro nidaamka xaalufinta ensaymka noolaha, isticmaal cyanide hydratase si aad ugu beddesho ion cyanide ee hadha una beddelo nitrogen ammonia aan dhib lahayn.

IV. Isbeddelka Warshadaha iyo Muuqaalka Mustaqbalka

1. Sahaminta Tiknoolajiyada Kale :

• Chitosan-ku-saleysan-ku-xirnaanta isku-xiran: Samee lakab ka-hortagga-yaraynta deegaanka u-saaxiibtiran iyada oo loo marayo fal-celin-is-daba-marin-is-daba-marin, oo leh heer-bayo-xumo ah 85%;

• Daaweynta Plasma: Isticmaal balaasmaha argon si aad u xoqdo oogada fiber-ka si aad u samayso qaab-dhismeed qallafsan oo nanoscale ah si loo xakameeyo yaraanshaha.

2. Casriyeynta Nidaamka Caadiga ah :

• Nooca dib loo eegay ee Xeerka REACH EU ee 2024 waxa uu taxayaa sodium cyanide oo ah walax walaac aad u sareysa leh (SVHC), oo dejinaya xadka 0.1mg/kg ee hara ee dunta;

• Golaha Qaranka ee Dharka iyo Dharka ee Shiinaha ayaa soo saaray "Tilmaanta Farsamada ee Dhammaystirka Ka-hortagga Yaraynta Cagaaran", isaga oo u baahan shirkadaha si ay u dhisaan nidaamka maaraynta deegaanka wareegga nolosha.

Ugu Dambeyn

Codsiga sodium cyanide ee duurka ka-hortagga dhar-xidhka dharka ayaa ka tarjumaysa is-dhexgalka qoto-dheer ee tignoolajiyada kiimikada iyo sayniska alaabta. In kasta oo ay soo food saartay cadaadiska ilaalinta deegaanka, iyada oo loo marayo hal-abuurnimada habka iyo adeegsiga hababka la socodka caqliga, qiimaheeda farsamo ayaa wali si joogto ah loogu sii dayn karaa qaab badbaado adag. Mustaqbalka, warshaduhu waxay dardar gelin doonaan isbeddelka xagga tignoolajiyada dhammaystirka bio-ku-salaysan iyo caqli-galnimada, kor u qaadista warshadaha dharka si ay u horumariyaan jihada tayada sare leh iyo waaritaanka weyn.
