Reductive removal of selenate (VI) in aqueous solution using rhodium metal particles supported on TiO.

Selenium and its compounds in high concentration are toxic for humans, especially selenate (VI) is the most toxic due to its high solubility in water. To promote the reductive reaction of Se(vi) to Se(iv) or Se(0), which is relatively easy to remove in water, noble metal particles were added as reaction sites with a reductant. The highest removal performance of selenate in aqueous solution was achieved using rhodium particles supported on TiO (Rh/TiO).

As(iii) removal through catalytic oxidation and Fe(iii) precipitation.

To remove arsenite (As(iii)) from wastewater effectively, the catalytic oxidation of As(iii) to arsenate (As(v)) and As(v) precipitation with iron ions (Fe(iii)) was investigated. The Pt/SiO catalyst functioned as a reaction site for As(iii) with oxygen in the atmosphere. The combination of the Pt/SiO catalyst and Fe(iii) precipitant improved the removal of As(iii) in the precipitate; Pt/SiO worked as both an As(iii) oxidation site and precipitation site with Fe(iii) precipitant.

[Does the nutritional care plan and report upon discharge under the health care system substitute the nutrition support team summary at patient discharge?].

Our nutrition support team (NST) designed the NST summary for cooperation among personnel providing medical care for nutritional management of high-need patients in our area. After the introduction of the NST fee under the health care system, the number of summary publications decreased. The requested NST fee is necessary for publication of a nutritional care plan and report upon patient discharge.
