Phosphorus is an essential nutrient for aquatic plants and animals. The acceptable range for phosphorus in water is from 0.01 to 0.03 mg/L. However excessive phosphorus use can result in biodiversity loss and pollution and endanger aquatic creatures and human health because the pollutants are non-biodegradable and thus accumulate over time. This work investigated phosphorus removal from synthetic wastewater containing KH2PO4 via calcined cockle shell waste adsorption. Phosphorus adsorption was studied by calcined cockle shell waste of less than 75 um particle size. Five adsorbent dosages (0.2,0.4,0.6,0.8,1.0g) mix with ten ppm phosphate were adsorbed for 60 min. The presence of calcined cockle shell waste was determined using scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), and a DR6000 UV-visible spectrophotometer. In brief, the highest dosage of 1.0g removed 94.96% phosphorus from the synthetic wastewater, while the most extended treatment time resulted in 95.74% phosphorus adsorption. The proposed method is low cost and convenient.
