A Simple Paper-Based Colorimetric Device for Rapid Mercury(II) Assay
Contamination of the environment by mercury(II) ions (Hg(2+)) poses a serious threat to human health and ecosystems. Up to now, many reported Hg(2+) sensors require complex procedures, long measurement times and sophisticated instrumentation. We have developed a simple, rapid, low cost and naked-eye quantitative method for Hg(2+) environmental analysis using a paper-based colorimetric device (P...
متن کامل[The evaluation of methods for determinations of urinary oxalate].
BACKGROUND Estimation of urinary oxalate is one of important tools for the diagnosis and treatment of urolithiasis. And more precise, simple and inexpensive method is desirable. In the present study, we evaluated three methods which were clinically well-used. METHODS From October 1996 to June 1997, 146 acidified urine samples were collected for 24 hours from 144 urolithiasis patients. We dete...
متن کاملEffect of tetrasodium EDTA on enzymatic determinations of urinary oxalate.
We studied the effects of pretreating urine samples with tetrasodium EDTA (TEDTA) before measuring urinary oxalate with an enzymatic kit (Sigma). Mean analytical recovery of added oxalic acid was only 49% (SD +/- 13%) when the assay was performed as recommended by the manufacturer, but treating samples with TEDTA improved recoveries (96 +/- 10%). In 20 unselected 24-h urine samples assayed with...
متن کاملA simple colorimetric device for rapid detection of Hg2+ in water.
A 'turn-on' fluorescent colorimetric device for Hg(2+) sensing was built using a dual light-emitting diode system. Fluorescence generated from a rhodamine derivative (RHD), an indicator for Hg(2+) sensing, was combined with a background red light, and the complex light was captured by a commercial charge coupled device camera or by the naked eye.
متن کاملRapid enzymatic determination of urinary oxalate.
This new reagent kit for the quantitative measurement of oxalate in urine is a modification of an earlier Sigma oxalate assay procedure (procedure no. 590), a coupled enzyme assay involving oxalate oxidase and horseradish peroxidase. The new analytical procedure includes methods for processing urine specimens to eliminate interference with oxalate color development at 590 nm by ascorbic acid, d...
