Chemical, Functional, and Structural Properties of Spent Coffee Grounds and Coffee Silverskin
Spent coffee grounds (SCG) and coffee silverskin (CS) represent a great pollution hazard if discharged into the environment. Taking this fact into account, the purpose of this study was to evaluate the chemical composition, functional properties, and structural characteristics of these agroindustrial residues in order to identify the characteristics that allow their reutilization in industrial ...
متن کاملCharacterization of polysaccharides extracted from spent coffee grounds by alkali pretreatment.
Spent coffee grounds (SCG), obtained during the processing of coffee powder with hot water to make soluble coffee, are the main coffee industry residues and retain approximately seventy percent of the polysaccharides present in the roasted coffee beans. The purpose of this study was to extract polysaccharides from SCG by using an alkali pretreatment with sodium hydroxide at 25°C, and determine ...
متن کاملSpent Coffee Grounds as Adsorbents for Pesticide Paraquat Removal from its Aqueous Solutions
Spent coffee grounds were evaluated for adsorption efficiency in the removal of pesticide paraquat from its aqueous solutions. The influence of the adsorbent mass, agitation time, paraquat concentration and pH have been investigated in the batch sorption mode. Adsorption capacity (mg/g) has been found to be 27.87 ± 1.57 mg/g, while the removal efficiency has resulted of 32.25 ± 1.79 %. Adsorpti...

متن کاملInvestigation of indium ions removal from aqueous solutions using spent coffee grounds
This study used batch adsorption techniques to evaluate the potential suitability of spent coffee grounds as an environmentally friendly adsorbent for the removal of indium ions from aqueous solutions. In addition, we also investigated the effects of process parameters, such as, the solution pH, adsorbent dose, initial concentration of indium ions and the temperature on adsorption performance. ...
