Colorimetric detection of Cr3+ in dietary supplements using a smartphone based on EDTA and tannic acid-modified silver nanoparticles

Sangsin S.; Srivilai P.; Tongraung P. (2021)

A simplistic, portable and low-cost method for the rapid detection of Cr3+ was developed based on a smartphone readout and a co-functionalized silver nanoparticles (AgNPs) system for use as an on-site device in resource-poor ...
Lab-on-paper with dual electrochemical/ colorimetric detection for simultaneous determination of gold and iron

Apilux A.; Dungchai W.; Siangproh W.; Praphairaksit N.; Henry C.S.; Chailapakul O. (2010)

A novel lab-on-paper device combining electrochemical and colorimetric detection for the rapid screening of Au(III) in the presence of a common interference, Fe(III), in industrial waste solutions is presented here. With ...
Simple flow system with in-line gas-diffusion unit for determination of ethanol employing hypsochromic shift of visible absorbance band of methyl orange

Ratanawimarnwong N.; Sinpun M.; Chankaw P.; Choengchan N.; Nacapricha D. (2020)

The effect of solvent composition on the uv–visible spectrum of methyl orange was investigated for application to the quantitative determination of ethanol. At fixed pH, there was a hypsochromic shift of the absorbance ...
