The aim of the study was to screen waste wood biomass 10 species as biosorbents for synthetic dye Congo Red (CR) removal from water and single out most efficient further batch biosorption experiments. Euroamerican poplar (EP), achieving 71.8% CR capacity 3.3 mg g−1, characterized by field emission scanning electron microscopy (FE-SEM) Fourier transform infrared spectroscopy (FTIR). Different factors affecting process were investigated: initial biosorbent concentration (1–10 g dm−3), contact...

The aim of the study was to prepare a novel adsorbent by chemical modification hazelnut shells and evaluate its potential for nitrate removal from model solutions real wastewater. characterization adsorbent, i.e., modified shell (MHS) performed. included analysis elemental composition surface characteristics scanning electron microscopy (SEM) Fourier transform infrared spectroscopy (FTIR). adsorption experiments (batch technique) were performed investigate effects concentration, contact...

Brewers' spent grain (BSG), a lignocellulosic waste material, was evaluated as low-cost adsorbent for the removal of synthetic dyes methylene blue (MB) and Congo red (CR) from aqueous solutions in batch process.Characterisation BSG performed by chemical analysis, FTIR SEM.The effects contact time, initial dye concentration, particle size, concentration pH on adsorption process were investigated.High both ranging 70 to over 90 % achieved.It shown that cases (MB CR adsorption) could be...

Blackberry wine is a natural source of bioactive phenolic compounds that have profound antioxidant potential. The objectives the present research were to assess and activity blackberry wines (BW), use chemometric analysis differentiate among two groups samples, i.e., conventional organic. Fifteen BW samples analyzed for their total polyphenol index, polyphenols, flavonoids, tannins, monomeric anthocyanins by appropriate spectrophotometric methods. concentrations individual acids (gallic...

The presence of heavy metals in an agricultural land is the primary cause food product toxicity a herbal and animal origin associated with contaminated land. anthropogenic sources pollution, especially fertilizers pesticides agriculture, are contamination metals. whose monitoring prescribed by current legislation Republic Croatia include cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb) zinc (Zn). aim this paper to provide review that land, as well remediation...

Since the synthetic dye Congo red and nitrate are notorious contributors to water pollution due their persistent potentially toxic nature, it is necessary develop new efficient methods remove them from bodies. Native lignocellulosic materials as biosorbents mostly inferior, i.e., adsorption capacities of native lower. Therefore, attempts have been made improve such by physical and/or chemical methods, including production biochar. In this study, adsorptive removal was investigated using a...

This study brings out the data on content of 21 mineral and heavy metal in 15 blackberry wines made conventionally organically grown blackberries. The objective this was to classify wine samples based their composition applied cultivation method starting raw material by using chemometric analysis. Croatian determined AAS after dry ashing. comparison between an organic conventional group investigated showed statistically significant difference concentrations Si Li, where contained higher...

Background and purpose: Wood wood processing industries are generators of a substantial amount waste biomass, such as chips, shavings sawdust.Such is often unused its disposal can be serious environmental problem.Different lignocellulosic materials have been successfully used low-cost adsorbents (biosorbents) for the removal synthetic dyes, well other contaminants, from wastewater.The aim this study was to valorise biomass ten tree species, out which seven most represented species Croatian...

The aim of this work was to investigate grape seeds as a potential adsorbent for nitrate removal from water. Grape were modified by quaternization and the applicability (MGS) evaluated in batch adsorption experiments. Fixed bed regeneration studies carried out determine capacity MGS. maximum 25.626 mg g−1 at native pH (6.3) MSG comparable that commercial anion exchange resin Relite A490 under similar conditions. percent model solution 86.47% 93.25% MGS, A490, respectively, synthetic...

Even though traditional raw materials used for beer production include only (barley) malt, hops, water and yeast, a whole range of un-malted adjuncts are also utilised (corn, oats, rice, rye) to get new speciality or merely cut down the expenses. Furthermore, particular consumers, health-related demands lead development types beer, such as gluten-free beer. Chestnut, material is considered be best substitute barley malt regarding its sensorial characteristics. The objective this preliminary...
