This work describes removal of hydrocarbons from aqueous solution using porcelanite as an adsorbent surface with investigation of some factors that affect on adsorption process of the hydrocarbons such as contact time, primary hydrocarbons concentration in the solution, adsorbent particle size and temperature of the solution. Removal of hydrocarbons was conducted using the batch method. From the obtained results, it was found that, the quantity of adsorbed hydrocarbons was increased with increase in adsorption temperature .Equilibrium time was attained at 30min for efficient removal of hydrocarbons. Removal percentage of hydrocarbons over porcelanite powder was found to be 41.61% and the amount of adsorbed hydrocarbons over porcelanite was 83.22(mg/g). The results of adsorption processes were more fitted with Friendlich model rather than Langmuir adsorption model. Thermodynamic study showed that, ΔH was endothermic, ΔG at the values were negative at lower concentrations and then turned positive when concentrations increased and ΔS was found to be positive.

“…Different temperature is 10.0, 25.0, 37.5 and 50.0 °C, were used for equilibration, with agitation rate of 120 rpm using an orbital shaker. The amount of ions adsorbed and removal percent of adsorbent depending on the difference between concentration of the ion before and after adsorption were obtained from equations ( 1) and (2) (Jain et al, 2019)…”

Ferrite nanoparticles (NPs) with structure NiFe2O4 were created following the sol-gel auto-combustion method using lemon juice as surfactant and fuel agent. This method is located within the green chemistry, a method of environmentally friendly and less expensive than other methods. Nanomaterial’s have been diagnosed using different physical and chemical techniques: Brunauer-Emmett-Teller (BET) analysis, Field Emission-Scanning Electron Microscopy (FE-SEM), Energy Dispersive X-ray Spectrosc0py (EDX), F0urier-Transform Infrared Spectroscopy (FTIR), Transmission Electr0n Microscopy (TEM) and X-ray diffraction (XRD). X-ray diffraction patterns confirmed the phase purity and the particle size 24.27nm. The effects of adsorbent concentration, pH, temperature, and time of contact on Lead and Cadmium ions uptake behavior were measured. The optimum time of contact to attain equilibrium is 60min for Lead (II) ion and 90 min for Cadmium (II) ion, and pH values are in the range (3-9). The results of adsorption showed a strong correlation with Freundlich model compared with the Langmuir model. The thermodynamic parameters were given, revealing endothermic reaction for ΔH, ΔG was found a spontaneous process and ΔS had positive value, increase of disorder of the process.

“…In the last few decades, rapid industrialisation has resulted in a high demand for energy, which is coupled with the depletion of natural resources [ 1 ]. The scientific community has focused their research towards developing new materials for various catalytic applications to store energy, which are safe and eco-friendly [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 ]. Materials based on carbon, i.e., graphite, fullerene, carbon nanotubes, and graphene, are an important choice due to their non-toxic nature [ 10 , 11 , 12 , 13 ].…”

Doping is a great strategy for tuning the characteristics of graphene-based nanomaterials. Phosphorous has a higher electronegativity as compared to carbon, whereas boron can induce p-type conductivity in graphene. This review provides insight into the different synthesis routes of phosphorous- and boron-doped graphene along with their applications in supercapacitors, lithium- ions batteries, and cells such as solar and fuel cells. The two major approaches for the synthesis, viz. direct and post-treatment methods, are discussed in detail. The former synthetic strategies include ball milling and chemical vapor discharge approaches, whereas self-assembly, thermal annealing, arc-discharge, wet chemical, and electrochemical erosion are representative post-treatment methods. The latter techniques keep the original graphene structure via more surface doping than substitutional doping. As a result, it is possible to preserve the features of the graphene while offering a straightforward handling technique that is more stable and controllable than direct techniques. This review also explains the latest progress in the prospective uses of graphene doped with phosphorous and boron for electronic devices, i.e., fuel and solar cells, supercapacitors, and batteries. Their novel energy-related applications will continue to be a promising area of study.
