-Biosorption potential of sunflower seed hull to remove reactive textile dye contaminated solutions was the purpose of this investigation. Azure A chloride dye was chosen as a model for this investigation. Pretreatment, initial pH, biomass dosage, contact time, initial dye concentration and temperature were evaluated in batch mode studies. Preliminary results indicate that acid and base pretrea...

Our study investigated the accumulation of chromium, nickel, lead and cadmium by maize (Zea mays L.), sunflower (Helianthus annuus L.), willow (Salix x smithiana Willd.), and poplar (Populus nigra L. x P. maximowiczii), and the realtionship between the contaminants in soil and in plants. The experiment was performed in contaminated soil (former waste incineration plant) at the Hradec Králové (C...

Introduction Sunflower seed is one of the most commonly consumed snacks in our country. Sunflower seeds are not only eaten as snacks but also are used as ingredients of breads, mueslies and bars in recent years. Sunflower seed allergy is seen rarely in children and may be presented as angioedema or anaphylaxis. Respiratory allergies have been reported previously in adults owning birds fed on su...

With sustainable energy being the key to reaching climate neutrality, utilization of non-wooden biomass is a necessity. This article compares emissions and efficiency combusting number types agrobiomass wood pellets. A comparison was made on moving grate pellet burner mounted in boiler, where flue gas had vertical flow via two pass heat exchangers with turbulization elements. Tests were conduct...

Raw algae waste naturally thrown on shores could pose serious threats for landfilling and its reuse composting or further processing as added-value by-products require knowledge-based decisions management the sustainable development of local ecosystems. marine containing salt (halite) heavy metals that eventually accumulate in hamper their safe applicability soil fertilization other exploitatio...

1 Sunflower (Helianthus annuus L.) is native to North America. American natives first cultivated sunflower 5000 yr ago in the present-day southwest United States (Semeslczi-Kovacs, 1975). Sunflower spread to the north and east in North America, where it was domesticated 4000 yr ago (Blackman et al., 2011). Sunflower is a relatively new commercial crop to the United States, with commercial culti...
