Analysis of Methylphenol Concentration in Selangor, Malaysia Rivers using Solid Phase Extraction Technique Coupled with UV-Vis Spectroscopy

Methylphenol is extensively produced from pharmaceuticals, agriculture, textiles, cosmetics, and petrochemicals industries. It is a pollutant that can adversely affect public health and the ecosystem. Following the issues raised, methylphenol extraction from Selangor rivers need to be done to avoi...
