Blato, obdelani biološki odpadki in tla - Razklop v zlatotopki topnih frakcij elementov
Ta evropski standard določa pripravo blata, obdelanih bioloških odpadkov in tal (vključno z materiali, ki so podobni tlom), ki so obravnavani v analizi organskih in anorganskih kemijskih in fizikalno-kemijskih parametrov. Priprava vzorcev je namenjena pripravi (majhnega) preskusnega vzorca, ki je reprezentativen za izvorni vzorec. V tem evropskem standardu sta opisani priprava, ki se lahko po potrebi izvede na prostem, in priprava vzorca v laboratorijskih pogojih. V tem evropskem standardu so za določitev anorganskih kemijskih in fizikalno-kemijskih parametrov opisani postopki za pripravo: – preskusnih vzorcev za preskuse v vlažnih razmerah na prostem; – preskusnih vzorcev za preskušanje po sušenju, drobljenju, mletju, sejanju itd.; – preskusnih vzorcev tekočega blata. Za določanje organskih spojin so opredeljene tri metode priprave: – metoda priprave v primeru merjenja hlapnih organskih spojin; – metoda priprave, če se merijo slabo hlapne do nehlapne organske spojine, pri čemer bo rezultat naslednje analize natančen in ponovljiv; – metoda priprave, če se merijo slabo hlapne do nehlapne organske spojine in je za postopek ekstrakcije potreben vzorec vlage na prostem ali če so potrebni samo nakazalni rezultati. Izbira metode je odvisna predvsem od hlapnosti analita. Odvisna je tudi od razporeditve delcev po velikosti materiala, raznovrstnosti vzorca in naslednjega analiznega postopka.

WARNING — Persons using this European Standard should be familiar with usual laboratory practice. The reagents used in this European Standard are strongly corrosive and partly very toxic. Safety precautions are absolutely necessary, not only due to the strong corrosive reagents, but also to high temperature and high pressure.
The use of laboratory-grade microwave equipment with isolated and corrosion resistant safety devices is required. Domestic (kitchen) type microwave ovens shall not be used, as corrosion by acid vapours may compromise the function of the safety devices and prevent the microwave magnetron from shutting off when the door is open, which could result in operator exposure to microwave energy.
All procedures shall be performed in a fume hood or in closed force-ventilated equipment. By the use of strong oxidising reagents, the formation of explosive organic intermediates is possible, especially when dealing with samples with a high organic content. Do not open pressurized vessels before they have cooled down. Avoid contact with the chemicals and the gaseous reaction products.
IMPORTANT — It is absolutely essential that tests conducted according to this European Standard be carried out by suitably trained staff.
