Selective and Preferential Separation of Rhodium (III) from Palladium (II) and Platinum (IV) Using a m-Phenylene Diamine-Containing Precipitant.

Although Rh is an industrially important and the most expensive platinum group metal (PGM), the selective and preferential separation of Rh from PGM mixtures still remains as a big challenge. In this work, the separation of Rh (III) from Pd (II) and Pt (IV) in a hydrochloric acid (HCl) solution was studied using a m-phenylene diamine-containing precipitant (m-PDA). At high HCl concentrations (6.

Early detection of colon cancer by amino acid profiling using AminoIndex Technology: a case report.

Most tumor markers have low detection rates for curable stages of cancer and are therefore not satisfactory for use in a healthy population. A new cancer risk calculation method, AminoIndex Cancer Screening (AICS), uses multiple plasma amino acid concentrations to calculate the risks for several cancers simultaneously and is suggested to have a high detection rate for early-stage cancers and a low false-positive rate for adenomas. Here, we describe a male patient with a family history of colorectal cancer who underwent AICS.
