Iodine Sampling With Silver Nitrate-impregnated Filter Paper

Iodine and creatinine testing in urine dried on filter paper.

Iodine deficiency is a world-wide health problem. A simple, convenient, and inexpensive method to monitor urine iodine levels would have enormous benefit in determining an individual's recent iodine intake or in identifying populations at risk for iodine deficiency or excess. Current methods used to monitor iodine levels require collection of a large volume of urine and its transport to a testi...

Antibacterial ethylene propylene rubber impregnated with silver nanopowder: AgNP@EPR

Following our interest in reaching for a molded rubber article with possible detergent contact applications, durable silver nanopowder (AgNP) is synthesized by arc discharge, then mixed with varying ratios of ethylene propylene rubber (EPR), affording novel AgNP@EPR nanocomposites. X-ray diffraction (XRD) patterns of AgNP as well as AgNP@EPR show no trace of impurity, while scanning electron mi...

The Agglutinatiun Test with Brucella Sera Absorbed into Filter Paper

Large-scale separation of fatty acid methyl esters by column chromatography on acid-washed Florisil impregnated with silver nitrate.

Sustainable colloidal-silver-impregnated ceramic filter for point-of-use water treatment.

Cylindrical colloidal-silver-impregnated ceramic filters for household (point-of-use) water treatment were manufactured and tested for performance in the laboratory with respect to flow rate and bacteria transport. Filters were manufactured by combining clay-rich soil with water, grog (previously fired clay), and flour, pressing them into cylinders, and firing them at 900 degrees C for 8 h. The...
