(Research Society of Chemistry, 2023)The ecosystem and human health are both significantly affected by the occurrence of potentially harmful heavy metals in the aquatic environment. In general, wastewater comprises an array of heavy metals, and the existence ... -
Removal of heavy metals from water by capacitive deionization electrode materials derived from chicken feathers
(NM-AIST, 2019-03)Capacitive deionization (CDI) is an emerging desalination technology based on the principle of electrical double layer capacitors. When the voltage is applied to the surface of the electrodes, electrodes become oppositely ... -
Removal of hydrogen sulfide and ammonia from biogas using Oldoinyo Lengai Volcanic ash
(NM-AIST, 2019-02)Oldoinyo Lengai mountain located in Northern Tanzania is the only active natrocarbonatite volcano with unusually alkali-rich natrocarbonatites which are not found elsewhere in the world. Volcanic ash formed earlier during ... -
Removal of Hydrogen Sulfide from Biogas Using a Red Rock
(Hindawi, 2020-01-27)The potential of red rock (RR) materials for the removal of H2S from biogas was studied. The rock samples were collected, sieved, and organized in various particle size ranges such as 0.32-250 μm, 250-500 μm, 500-750 μm, ... -
Removal of hydrogen sulfide from biogas using red rock materials
(NM-AIST, 2020-03)In this study, the potential of red rock materials for the removal of hydrogen sulfide from biogas was studied. The rock samples were collected, sieved and organized in various particle size ranges such as 0.32 - 250 µm, ... -
Removal of hydrogen sulfide from biogas using sweet potato’s leaves derived activated carbon
(NM-AIST, 2020-04)Hydrogen sulfide gas contained in biogas is both corrosive and poisonous. In this study a performance of sweet potato leaves activated carbon for hydrogen sulfide removal from biogas was evaluated. The samples were ... -
Removal of lamivudine from synthetic solution using jamun seed (Syzygium cumini) biochar adsorbent
(Emerging Contaminants, 2023-09-01)Antiviral drugs such as lamivudine have been globally identified in the environment and marked as emerging pollutants of concern due to their bioactive extremity. Following therapeutic uses, approximately 70% of the oral ... -
Removal of Selected Heavy Metal Ions from Industrial Wastewater Using Rice and Corn Husk Biochar
(Springer Nature Switzerland AG., 2020-05-12)This study investigated the removal of heavy metal ions from industrial wastewater by using rice and corn husk biochar. The choice of the materials was influenced by their large surface area, abundance of functional groups ... -
Representation of seasonal land use dynamics in SWAT+ for improved assessment of blue and green water consumption
(Hydrology and Earth System Sciences, 2022-08-29)In most (sub)-tropical African cultivated regions, more than one cropping season exists following the (one or two) rainy seasons. An additional cropping season is possible when irrigation is applied during the dry season, ... -
Response surface optimization and modeling in heavy metal removal from wastewater—a critical review
(Springer Nature, 2022-04-08)The existence of hazardous heavy metals in aquatic settings causes health risks to humans, prompting researchers to devise effective methods for removing these pollutants from drinking water and wastewater. To obtain optimum ... -
A Review of Methods for Removal of Ceftriaxone from Wastewater
(MDPI, 2022-08-02)The presence of pharmaceuticals in surface water and wastewater poses a threat to public health and has significant effects on the ecosystem. Since most wastewater treatment plants are ineffective at removing molecules ... -
