Metodes cinka oksīda nanodaļiņu koncentrācijas novērtēšanai ūdens šķīdumā

Eva Trumsiņa, Silvija Kukle

Abstract


Šī pētījuma galvenais mērķis ir veikt cinka oksīda nanodaļiņu koncentrācijas novērtēšanu ar divām metodēm (GDV kamera un konduktometrs) un iegūt rezultātus salīdzinošu analīzi. Divu piedāvāto tehnoloģiju analīze parāda, ka, salīdzinot mērījumos iegūto bioelektrogrammu vidējos laukumus vai vidējos izolīniju garumus, iespējams noteikt metālus saturošu nanodaļiņu koncentrāciju, ja tā ir ne mazāka par 1 masas %. Ja sagaidāmā koncentrācija ir zema, šķīduma īpatnējās elektrovadītspējas mērījumi ar konduktometru ļauj precīzi noteikt nanodaļiņu koncentrāciju.

Keywords:

Cinka oksīds; nanodaļiņas; koncentrācijas noteikšana; konduktometrs
