For my extended essay, I was quite certain that I wanted to do something in Chemistry that involves a series of experiments that would put my lab skills to test. Hence I began to do some preliminary research on potential extended essay topics in the subject of Chemistry. After conducting some research, I came across this topic pertaining to biosorption of heavy metal ions by red algae. This immediately struck a chord inside me as I have never thought that an experiment like this could be carried out and after conducting further research, I managed to narrow down my research question and take note of how temperature manages to play a role in the amount of lead adsorbed by red algae. Lead has the potential of causing brain damage if consumed while present in water, hence this experiment comes as a cheaper alternative to purification techniques that are not so cost effective. Despite managing to get a base for my EE, it is time to consolidate it by carrying out some more research regarding past experiences with this particular experiment to see what would be the best way for me to carry it out.
