A simple, efficient, and abundantly available agricultural waste material, banana pseudo-stem (BPS) was examined as raw
material for the extraction of potassium. The effects of various process parameters such as temperature, initial pH, contact
time, banana pseudo-stem dosage and size of banana pseudo-stem particles on potassium extraction efficiency were studied by
running batch experiments in Erlenmeyer flasks. Response Surface Methodology (RSM) was used to design the experimental
runs. Modelling and optimization of process variables to obtain maximum extraction of potassium from raw material were done
using RSM.The maximum extraction efficiency of potassium was found to be 83.96% at a temperature of 400C, pH of 1, contact
time of 30 min, BPS weight of 26.076 g and initial BPS size of 300.The results revealed that banana pseudo-stem can be used as
good source for potassium extraction.
