Abstract

Inventia se refera la o metoda pentru determinarea cianurilor din ape, conform careia proba este adusa la pH alcalin si iradiata cu lumina ultravioleta având lungimea de unda de 290 ... 400 mmiu, obtinuta prin filtrarea luminii ultraviolete emisa de sursa, acidularea probei indicate, supunerea ei la distilare si masurare colorimetrica a cianurii recuperate. Instalatia folosita cuprinde un bloc de iradiere a probei de analizat, continând o lampa cu ultraviolete, înconjurata de un tub de sticla si o serpentina de sticla, legata de un evaporator în film subtire, între blocul de iradiere si evaporator fiind introdus amestecul de acid si acidul cianhidric îndepartat din evaporator si apoi amestecul este alimentat la serpentina de absorbtie, care este legata la o conducta de recirculare, si o serpentina de cloramina-T introdusa în serpentina de amestecare, în care este introdus reactivul de culoare, serpentina fiind legata, prin intermediul serpentinei de amestecare, la un colorimetru având o conducta de descarcare, semnalul obtinut fiind preluat de unitatea de înregistrare.
