| contents | In this work, Ag0 nanoparticles (NPs)were synthesized and detected by flow-injection analysis coupled to collinear dual-beam thermal lens spectrometric (TLS) detection. The estimated limit of detection was 0.8 microgram/L. The use of 2 the IonPac Cryptand G1 column enabled Ag0 NPs detection in the presence of interfering ions normally present in water. Ag0 nanofluids (NFs) were further characterized by time-resolved TLS and beam deflection spectrometry to determine the NFs thermal diffusivity and conductivity. The applied methods were found to be fast, simple,reliable, and highly sensitive. |
