Frequently Asked Question

A final year project on utilizing coconut husk as a low-cost adsorbent for removing methylene blue, methylene orange, and tetracycline would be an excellent choice! Here's a potential framework:
1. Introduction
Briefly discuss the environmental impact of dyes and antibiotics like methylene blue, orange, and tetracycline.
Highlight the need for cost-effective and sustainable methods of removing these pollutants from water.
Introduce coconut husk as a readily available and low-cost adsorbent material.
2. Literature Review
Explore existing research on the adsorption of dyes and antibiotics onto various adsorbents, focusing on coconut husk and its potential.
Examine the adsorption mechanisms, factors influencing adsorption (e.g., pH, temperature, adsorbent dosage), and characterization techniques used for adsorbent materials.
