Adsorption of Methylene Blue from Aqueous Solution Using Steam-Activated Carbon Produced from <i>Lantana camara</i>Stem

Journal of Environmental Protection 2014年第13期5卷 1352-1363页

This study investigated the adsorption of Methylene Blue (MB) present in wastewater onto the activated carbon produce from Lantana camara stem. The agricultural material (Lantana camara stem) was carbonized at 300°C for 2 h, ground and steam-activated. The Steam-Activated Lantana camara (SALC) stem carbon was characterized using Scanning Electron Microscope (SEM) and Fourier Transform Infrared (FTIR) Spectrophotometry before and after adsorption. Batch model experiments were conducted at 20°C to study the effects of pH, agitation time, adsorbent dosage and initial concentration of methylene blue. The equilibrium adsorption isotherms and kinetics were investigated. The FTIR bands at 3500, 2500, 2196 and 1682 cm-1 were shifted to 3646.3, 3030, 2822, 1709.05 cm-1 after MB adsorption. Similarly, the Scanning Electron Microscopy (SEM) analysis showed that the average pore size on the activated carbon was 20 μm. The Methylene Blue (MB) uptake increased with the increase in pH. Similarly, the dye adsorption increased as contact time increased, and reached equilibrium at 60 minutes. The removal of the dye increased when the dosage was increased from 0.5 - 2.0 g·L-1, at different dye concentrations (50 - 200 mg·L-1). The percentage removal decreased with increasing initial dye concentration for SALC. The adsorption isotherm data fitted well to the Freundlich isotherm (R2 = 0.989) while the experimental data fitted very well to the pseudo-second-order kinetic model (R2 = 0.99). This study suggests that adsorbent prepared from Lantana camara stem can be used effectively for the adsorption of methylene blue in wastewater.

Equilibrium, Kinetic and Thermodynamics Studies of Adsorption of Aniline Blue from Aqueous Media Using Steam-Activated Carbon Prepared from <i>Delonix regia</i>Pod

引用

Journal of Water Resource and Protection 2015年第15期7卷 1221-1233页

作者： Segun Akanmu Adebisi Omotayo Sarafadeen Amuda Ayoade Lateef Adejumo akeem olusegun olayiwola Abolaji Grace Farombi Analytical/Environmental Chemistry Unit Department of Pure and Applied Chemistry Ladoke Akintola University of Technology Ogbomoso Nigeria Department of Chemical Sciences Osun State University Osogbo Nigeria Department of Science Laboratory Technology Osun State Polytechnic Iree Nigeria

The adsorption capacity of steam activated carbon prepared from Delonix regia pods SADRC for adsorption of Aniline Blue (AB) from aqueous solution was investigated under various experimental conditions. Batch study was conducted to assess the potential of the activated carbon for the removal of Aniline Blue from aqueous solution. Activated carbon prepared from Delonix regia pods was characterized using Scanning Electron Microscope (SEM) and Fourier Transform Infrared (FTIR) Spectrophotometry before and after adsorption. The FTIR, spectra of SADRC pod before and after Aniline Blue adsorption were compared to study the impact of the Aniline Blue on the activated carbon developed from the Delonix regia pod. The stretching vibration band at 2169.54 cm-1 may be due to strong CN, while the stretching vibration band at around 1580 - 1650 cm-1 may be due to C=C stretching vibration. The bands around 1350 and 426.49 cm-1 are due to C-N and –SO3H group, respectively;this further suggests that some functional groups may be present on the surface of the carbon due to the low temperature of carbonization (300°C) of the adsorbent. Equilibrium isotherm studies were carried out by varying the following four parameters: initial concentration of Aniline Blue dye solution, solution pH and adsorbent dose. The equilibrium data obtained were more fitted to Langmuir than Freundlich isotherm models. The correlation coefficient value (R2) of the pseudo first order kinetics ranged from 0.08 to 0.85 while the R2 of the pseudo second order kinetics ranged from 0.963 to 0.997 at all the temperatures and initial concentrations considered. This suggests that the adsorption kinetics of Aniline Blue onto SADRC can be represented with pseudo second order kinetic model. This study showed that Delonix regia pod could be effectively used as an adsorbent for the removal of Aniline Blue from aqueous solutions over a wide range of concentration and temperature.

Trends of Temperature and Signature of Solar Activity in Selected Stations in Nigeria

Atmospheric and Climate Sciences 2014年第2期4卷 171-178页

作者： Christiana F. olusegun akeem B. Rabiu Jared O. H. Ndeda Emmanuel C. Okogbue Center for Atmospheric Research National Space Research and Development Agency (NASRDA) Kogi State University Campus Anyigba Nigeria Department of Meteorology Federal University of Technology Akure Nigeria Department of Physical and Chemical Sciences Elizade University Ilara-Mokin Nigeria Department of Physics Jomo Kenyatta University of Agriculture and Technology Nairobi Kenya

This study investigates the variability and periodicity of minimum temperature, maximum temperature and sunspot number—a solar activity index in selected synoptic stations across Nigeria from 1946 to 2010. Annual and semiannual effect of solar activity on minimum temperature was observed in all the six stations. This was indicated in the occurrence of modal periodicities of 6-month and 12-month observed across the six synoptic stations. The synoptic stations are Sokoto (13.01°N, 5.15°E), Ilorin (8.29°N, 4.35°E), Ikeja (6.35°N, 3.20°E), Enugu (6.28°N, 7.33°E), Port-Harcourt (4.51°N, 7.01°E) and Maiduguri (11.51°N, 13.05°E). Similarly, the trends of inter-decadal va-riability of minimum and maximum temperature show a non-uniformity increase over the analyzed period with a slight decrease before 1960. The long term behavior of minimum and maximum temperature shows a warming rate which ranges from 0.1°C/decade to 0.2°C/ decade across the six stations except for maximum temperature at Ilorin and minimum temperature at Sokoto which is at -0.2°C/decade and 0.3°C/decade respectively.
