Abstract

A filtration technique with 1,75% m/v chitosan membranes crosslinked with glutaraldehyde (0,08% v/v) was used to quantify the removal capacity of chromium, copper and cadmium ions from water. A simple and low cost filtration system was developed to use with prepared membranes.

The main goal was to use biodegradable materials for removing heavy metals from water, through a low energy consumption, cheap, and specific method.

As a result, two data sheets were prepared for the membranes. It was found out that chromium was the metal with the highest removal from water, by using a crosslinked membrane. Metal adsorption was best adjusted to the Freundlich isotherm model, better than Langmuir isotherm model.

However, it was found no correlation between pore size and crosslinking degree.
