Per a obtenir el t\u00edtol de CFGS en Qu\u00edmica Ambiental, a m\u00e9s d\u2019aprovar la part te\u00f2rica, s\u2019han de realitzar 440 hores en un centre de treball.\u00a0<\/span>En el meu cas, he tingut la sort de dur a terme les pr\u00e0ctiques a la facultat de farm\u00e0cia de la UB, simult\u00e0neament amb els estudis.\u00a0E<\/span>stic ajudant al Doctor Joan Romany\u00e0 en el seu projecte de recerca i estic molt contenta ja que encara que les pr\u00e0ctiques s\u00f3n guiades\u00a0cont amb molta autonomia i sempre se’m t\u00e9 en compte.<\/span><\/p>\n

Durant el temps que he estat en el laboratori he dut a terme activitats molt diverses, aix\u00ed que avorrir-se \u00e9s impossible.\u00a0<\/span>Principalment, la meva tasca ha consistit en analitzat l\u2019efecte que suposa un incendi per a les propietats del s\u00f2l i als seus microorganismes…<\/span><\/p>\n

<\/p>\n

El primer que he fet ha set simular les condicions de l\u2019incendi, aplicant diferents temperatures a un s\u00f2l i d\u2019aquesta manera observar quins s\u00f3n els canvis que suposa sobre el s\u00f2l inicial.<\/span><\/p>\n

Per a poder realitzar conclusions, he analitzat diferents par\u00e0metres com s\u00f3n el carboni org\u00e0nic i el total, el nitrogen, i el f\u00f2sfor.<\/span><\/p>\n

Actualment, estic duguent a terme la determinaci\u00f3 del f\u00f2sfor de les diferents terres per a veure quina quantitat ha quedat disponible. <\/span><\/p>\n

Per a veure quin \u00e9s el f\u00f2sfor disponible, el primer que he fet ha set analitzar el f\u00f2sfor inorg\u00e0nic mitjan\u00e7ant la seva extracci\u00f3 amb una soluci\u00f3 alcalina de bicarbonat de sodi, tamponada a pH 8.5. Posteriorment he agitar les mostres durant mitja hora y les he filtrar. Una vegada filtrat, amb ajuda d\u2019un matr\u00e0s de 25mL he estret una al\u00edquota de 5mL de cada extracte i li he afegit 3 gotes de p-nitrofenol, preparat anteriorment, que serveix com a indicador de pH. S\u2019ha d\u2019ajustar amb un parell de gotes de H<\/span>2<\/span><\/sub>SO<\/span>4<\/span><\/sub> fins que la mostra perd el color groc intens del p-nitrofenol al arribar a pH 5. Una vegada ajustat el pH he afegit un reactiu cromog\u00e8nic que desenvolupa un color blau, que \u00e9s m\u00e9s intens com m\u00e9s concentraci\u00f3 de f\u00f2sfor hi ha. <\/span><\/p>\n

Aquest mateix procediment, tamb\u00e9 l\u2019he dut a terme amb diferents patrons per poder realitzar una recta de calibratge.<\/span><\/p>\n

I per \u00faltim, el que he fet ha set mesurar l\u2019absorb\u00e0ncia en el espectrofot\u00f2metre a 882 nm, per poder saber, a partir de la recta de calibratge, la concentraci\u00f3 de f\u00f2sfor en els diferents s\u00f2ls.<\/span><\/p>\n

\"\"<\/a><\/p>\n

Una vegada obtingut el P inorg\u00e0nic el que s\u2019ha de fer \u00e9s determinar el total per poder obtenir l\u2019inorg\u00e0nic restant els dos anteriors.<\/span><\/p>\n

En aquest cas, el procediment \u00e9s pr\u00e0cticament igual per\u00f2 en lloc de fer l\u2019extracci\u00f3 amb una soluci\u00f3 alcalina, l\u2019he fet una H<\/span>2<\/span><\/sub>SO<\/span>4<\/span><\/sub> i una soluci\u00f3 oxidant. A continuaci\u00f3 he posat les mostres a l\u2019autoclau a 120\u00baC, durant 30 minuts i una vegada fredes, he passat 5 mL a un matr\u00e0s de 25 mL i he realitzar la resta, de la mateixa manera que amb el f\u00f2sfor inorg\u00e0nic.<\/span><\/p>\n

\"\"<\/a><\/p>\n

Aix\u00f2 nom\u00e9s \u00e9s una petita mostra del que he fet per a veure de quina manera afecta un incendi a un s\u00f2l, tant amb el que respecta als seus components com organismes vius que cont\u00e9.<\/span><\/p>\n

Les\u00a0FCT, m’han donat l’oportunitat de posar en pr\u00e0ctica el que he apr\u00e9s a classe i agafar m\u00e9s confian\u00e7a en el laboratori. A m\u00e9s, al fer feina en una facultat amb m\u00e9s gent, he apr\u00e9s a treballar en equip i a solucionar, entre tots, els problemes que es presentassin en el projecte.<\/p>\n","protected":false},"excerpt":{"rendered":"
