Decolourisation of malachite green dye by potassium carbonate-treated kernel shell adsorbent

The present study attempts to utilise potassium carbonate-treated kernel shell adsorbent for the decolourisation of malachite green solution. The adsorbent was characterised using FESEM, surface area analyser and FTIR. The bottle-point-technique was used to evaluate the adsorptive characteristics of...
