Determination of chlorogenic acid content in beans and leaves of coffea arabica using UV/Vis spectrometer
Chlorogenic acid (CGA) is one of the compounds found in coffee beans and other parts of coffee plant. However, its relative content in different coffee plant parts is least researched. Therefore, this study was designed to determine the contents of CGA in coffee leaves and beans. Green coffee beans and leaves were collected from South part of Ethiopia to study the content of CGA using UV/Vis spectrometer with...

Adsorption of chromium by brewers spent grain -g- poly (acrylic acid-co-acryl amide) from electroplating effluent
Toxic metal ions have lethal effects on all forms of life and these metal ions could enter the food chain when untreated waste effluents are discharged into the environment. In recent years, the use of low-cost adsorbent materials has been widely investigated in search of replacement for the costly methods that are currently used for removing these toxic metal ions from waste streams. In this study, the remediation of...
