Hi, me and my team mates are currently planning to pursue the topic of Activated Carbon from Coconut as a Water Filter. And we would like to ask for your suggestions and knowledge on what specific concepts are still underexplored in the said topic. We heard that this study is mostly common and we would like to know if there are still areas that need to be improved in the existing studies so we may have an idea on where to focus our study on. Your suggestions are very much appreciated. Thank you.
