Sorption of selected pharmaceuticals and pesticides on different river sediments.

In the present work, the sorption ability of 17 pharmaceutical compounds, two metabolites, and 15 pesticides (34 target compounds in total) onto four different river sediments was investigated separately. Selected compounds present the most frequently prescribed pharmaceuticals in human and animal medicine and the most frequently used pesticides in agriculture. Their presence into the surface, ground, and waste waters was confirmed into the numerous papers in literature, as well as their presence into the river sediments (for some of them).

Alkali modified hydrochar of grape pomace as a perspective adsorbent of Pb(2+) from aqueous solution.

Hydrochar produced via hydrothermal carbonization of grape pomace was considered as novel sorbent of Pb(2+) from aqueous solution. In order to enhance the adsorption capacity, hydrochar was chemically modified using 2 M KOH solution. Both materials were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy and X-ray diffraction technique.

Cardiovascular drugs in environmental waters and wastewaters: method optimization and real sample analysis.

A sensitive method for determination of the eight most prescribed drugs used in combined cardiovascular therapy in Serbia was developed and optimized. The method was based on SPE followed by LC/ion trap-MS/MS with positive electrospray ionization. Parameters that affect the SPE were optimized, such as the eluent, sample pH, and sample volume.
