The changes in pH and conductivity during the rinsing of the pumpkin peel and the biosorption of Cu2+ ions were the subject of this work. The obtained data showed that the pH value of the solutions increased during the rinsing of the biosorbent, as a result of the transfer of H+ ions from the aqueous phase into the structure of the pumpkin peel. An...

To analyze the co-combustion process of coal and biomass in a steam boiler furnace originally designed for pulverized coal combustion, it is crucial first to investigate the dynamic behavior of particles within the aero-mixture channels. Due to differences in material properties and particle size distributions, the behavior of coal and biomass part...

This study evaluates three hybrid electrocoagulation (EC) processes with aluminium electrodes:EC-zeolite process (EC+Z), EC-zeolite-ultrasound-assisted process (EC+Z+US), and EC-zeolitemagnet-assisted process (EC+Z+MAG) for compost wastewater treatment with a large content oforganic matter. The focus was on evaluating the effects of these processes...

Phytoremediation with wild plant species could be an environmentally friendly and economicalsolution. Selected wild plants like mint, oregano, chamomile, nettle, and St. John’s wort, from ruralareas in Bosnia and Herzegovina, were collected, lyophilized, and acid-digested for heavy metalsanalysis. Nickel (Ni), copper (Cu), chromium (Cr), cadm...
