Determination of trace heavy metals in herbs by sequential injection analysis-anodic stripping voltammetry using screen-printed carbon nanotubes electrodes

Injang U.; Noyrod P.; Siangproh W.; Dungchai W.; Motomizu S.; Chailapakul O. (2010)

A method for the simultaneous determination of Pb(II), Cd(II), and Zn(II) at low μgL-1 concentration levels by sequential injection analysis-anodic stripping voltammetry (SIA-ASV) using screen-printed carbon nanotubes ...
Electrical properties of bismuth germanate (Bi2GeO5) ferroelectric glass-ceramics prepared by two different methods

Panyata S.; Eitssayeam S.; Rujijanagul G.; Tunkasiri T.; Munpakdee A.; Pengpat K. (2019)

Ferroelectric Bi2GeO5 glass-ceramics were fabricated using conventional and incorporation method. Glasses have been prepared from BiO1.5-GeO2-BO1.5 ternary glass system by focusing on the region of 59 mol%BiO1.5: 23 mol%GeO2: ...
Electrochemical sensors for the simultaneous determination of zinc, cadmium and lead using a Nafion/ionic liquid/graphene composite modified screen-printed carbon electrode

Chaiyo S.; Mehmeti E.; Žagar K.; Siangproh W.; Chailapakul O.; Kalcher K. (2016)

A simple, low cost, and highly sensitive electrochemical sensor, based on a Nafion/ionic liquid/graphene composite modified screen-printed carbon electrode (N/IL/G/SPCE) was developed to determine zinc (Zn(II)), cadmium ...
Ferroelectric glass-ceramics from the PbO-Bi2O 3-GeO2 system

Munpakdee A.; Pengpat K.; Tunkasiri T.; Holland D. (2008)

The glass ceramics from the PbO-Bi3O2-GeO2 system have been investigated. An excellent transparent glass can be obtained from the stoichiometric (S) composition, Pb3Bi2(GeO 4)3, but only by rapid-quenching to give very ...
High sensitivity and specificity simultaneous determination of lead, cadmium and copper using μpAD with dual electrochemical and colorimetric detection

Chaiyo S.; Apiluk A.; Siangproh W.; Chailapakul O. (2016)

A bismuth-modified electrode can increase the sensitivity of lead and cadmium detection. However, use of a bismuth-modified electrode in the detection of copper remains limited because the bismuth signal overlaps with the ...
