“…Most of the research conducted lately made use of agricultural product such as adsorbent in the removal of heavy metals from water and wastewater, such agricultural products are coconut shell and rice husk [26,27], palm kernel shell, and oil palm fruit fiber [28], bamboo [3,29], maize cob [6]. Other works had been done on the identification and remediation of organic contaminants in petroleum [30][31] and pharmaceutical wastes [32][33] but few works have been done on the use of adsorbents in remediating organic pollutants (PAHs and EOCs).…”

Water is essential to human consumption; however, its pollution is caused by populace activities from both organic and inorganic compounds sources that require serious attention, to provide clean water. Organic contaminants are known as persistent organic pollutants (POP). They are accumulated in the fat tissues of wildlife and human beings and are toxic to their organs. Degradations of POP are very difficult since they are persistent and also termed as semi-volatile, for example, polycyclic aromatic hydrocarbons (PAHs). Apart from POPs, others toxic organic contaminants with subtle ecological effects are the emerging organic contaminants (EOCs), like pharmaceutical actives contaminants (PhACs). They penetrate the aquatic environment and alter the natural quality. To obtain future discharge requirements, new technologies with granular activated carbon were developed using Oxytenanthera abyssinica and Bambusa vulgaris in remediating PhACs and PAHs. The activated carbon with KCl had removal efficiency of 73.3, 78.1, and 86.2%, which indicated the highest efficiency for PhACs removal, while adsorbent activated with H3PO4 gave 63.9, 66.7, and 82.2% for paracetamol, salbutamol, and chlorpheniramine, respectively. Removal efficiency of 42.5–81.2% and 8.9–65.5% ranges of PAHs were obtained for CBV and COA, respectively. The alternative adsorption treatment techniques are detailed in the chapter.

Kinetics and thermodynamic studies were carried out for the removal of heavy metals (Pb +2 , Ni +2 and Cd +2) from aqueous solution by using Pennisetum glaucum. Surface morphology and elemental analysis were investigated with scanning electron microscope and energy dispersion X-ray spectroscope analysis. Functional group characteristics were found by a Fourier transform infrared spectrophotometer. The identified groups as binding sites for metal ions were found to be carbonyl (C=O), hydroxyl (OH) and amide (NH). Process parameters such as biosorbent dose, contact time, solution pH, initial metal ion concentration and so on were also studied in batch mode. The optimum pH for the studied process was found to be 5-6. Equilibrium data obtained from the batch process fitted well with the Langmuir isotherm and the process followed pseudo second-order kinetics. P. glaucum was found to be economical, ecofriendly and an effective biosorbent in sequestration of heavy metals from water.

Remediation of emerging pollutants is an aspect of environmental research with sparse information and knowledge, and the disposal of, these pollutants to the environment are mostly unregulated and on the increase. In view of this, the study examined the adsorptive capacity of adsorbent produced from Oxytenanthera abyssinica (COA 350°C KCl) and Bambusa vulgaris (CBV 350°C H3PO4) in remediating Pharmaceutical actives contaminants (PhACs) and polycyclic aromatic hydrocarbons (PAHs). Fourier Transform Infrared Spectroscopy, Scanning Electron Microscopy, Energy Dispersive X-ray were used in characterizing adsorbents. Derivative form of Solid Phase Extraction (SPE) and Liquid-Liquid extraction procedures were used for extracting selected PhACs and PAHs from sampled solutions respectively. Batch experiments were performed to study the adsorption capacity of adsorbents at varying contact time of 30min, 2hrs and 12hrs for PAHs and 30, 180, 360, 720 and 1440 mins for PhACs. Analysis of PhACs and PAHs concentrations for each sampling were determined by UV spectrophotometer and GC-MS respectively. The samples showed sharp absorption peaks at 3432 and 1632 cm−1 indicating O-H stretched and N-H stretched. The adsorbents showed both open and close pores. Carbon, Oxygen and Nitrogen in the adsorbent for CBV were 62.00, 33.53 and 3.98 and COA were 71.00, 22.80 weight percent, respectively. The adsorbents had good surface areas, pore volumes and pore sizes. Removal efficiency of COA showed the highest efficiency for PhACs removal at (73.3%, 78.1% and 86.2%) while CBV (63.9 %, 66.7% and 82.2%) for paracetamol, salbutamol and chlorpheniramine, respectively. CBV and COA ranged from 42.5-81.2% and 8.9-65.5% for PAHs removal respectively. The experimental result showed that adsorbents made from Oxytenanthera abyssinaca and Bambusa vulgaris can efficiently adsorb selected PhACs and PAHs in industrial Contaminated Water.
