The contamination of the environment by organic pollutants is a major risk factor, particularly for developing countries. Selected (SOPs) like phenolic compounds, polyaromatic hydrocarbons (PAHs), pesticides, and herbicides pose serious environmental health issues owing to their toxic characteristics poor degradability. Apart from potential mutagenicity, carcinogenicity, tetragenicity high body accumulation, these have become an increase concern worldwide. Biosorption promising alternative...
The intention of this study was to explore the efficacy and feasibility for Cu (II) adsorption onto fixed bed column maize tassel-PVA beads.The effects flow rate height were explored.The Thomas, Adams Bohart Yoon-Nelson models analysed evaluate performance.The constant correlation coefficient associated each model calculated.Thomas indicated that increase in increased values k Th q o .Thereafter, value decreased with decreasing height.With Adam-Bohart model, AB as continued decrease...
In the present work P-ZrO2CeO2ZnO nanoparticles were synthesised for first time using phytochemical extracts from Flacourtia indica leaves and applied in photocatalytic degradation of Congo Red presence Light Emitting Diode warm white light. The was optimized with respect to nanoparticle dosage, initial concentration, time. optimum conditions synthesis pH 9, F. dosage 4 g 100 mL-1, Zirconia, Cerium Zinc metal ion concentration 0.05 mg/L plant volume ratio 1:4. extract had most significant...
Problem statement: Major adsorbent materials used in heavy metal ion removal from polluted aqueous streams are expensive and difficult to regenerate. In this study, the possibility of using Zea mays tassel, as an alternative low cost biosorbent material remediate pollution was investigated. Lead (II) because its wide application industrial products well documented toxicity. Approach: Tassel obtained mature cultivar R52 hybrid plants. The tassel milled a powder adsorb lead(II) ions simulated...
This research employed the application of metal organic frameworks (MOFs) zinc and copper-based materials in removal naphthalene anthracene. Naphthalene anthracene adsorption were investigated with both zinc-benzene-1,4-dicarboxylic (Zn-BDC) copper-benzene-1,4-dicarboxylic (Cu-BDC) MOFs. Langmuir, Freundlich Temkin isotherms used to investigate mechanisms data obtained. Zn-BDC Cu-BDC MOFs stable at a wide range temperatures they exhibited appreciable desorption regenerating ability. About...
Cooling and freezing can be used to produce fresh water from brackish water, industrial brines leachates wastes.The aim of this study was identify how cooling and/or for the recovery drinking sulphate rich solutions associated with various cations.It found that: (i) If solution contains only Na 2 SO 4 , after pre-treatment sodium alkalis, it removed through down 0.33 mol/L (31.7 g/L ) crystallization •10H O; (ii) solubility upon is influenced by Clconcentration; (iii) Reverse Osmosis-Cooling...
Rooibos (Aspalathus linearis) plants are cultivated for the production of tea. In this work, biosorption process Pb(II) from aqueous solution on shoot powder (RSP) was studied in a batch process. The effect experimental parameters such as pH (2–9), contact time (30–180 min) and initial concentration (25–400 mg L−1), adsorbent dosage (0.2–2.1 g), temperature (25–80°C) examined. an attempt to determine capacity rate removal, isotherm kinetic data were modeled using different equations. To end,...
AbstractFreeze desalination of synthetic brines prepared from sodium chloride was investigated. Brine solutions levels between 2.3% to 10% were used as feed the plant operated in a batch and continuous mode. The effects pump, gear motor speed, differential temperatures on ice formation purity HybridICE process produced quality 80–96% purity. It observed that pump speed directly proportional effluent flow rate coming out heat exchangers. Generally, it product higher at low medium rates feed....
Mining activities are the main cause of generation voluminous sludge waste, loaded with metals precipitated from treatment acid mine drainage (AMD) and this is always disposed to landfill. This study aimed at characterizing suggesting reusability potential AMD reduce environmental problem caused by its accumulation so that it could become a valuable material. The was obtained after treating synthetic green oxidant sodium ferrate (VI) (Na2FeO4) prepared wet oxidation method. Chemical physical...
