“…The higher molar ratio is required to complete the reaction at higher rate. In lower molar ratio it takes longer time to complete .The most often used molar ratio of methanol to oil and KOH amount are 6:1 and 1%, respectively (Panneerselvam et al, 2011). This was found to be optimum in the present experiments leading to a satisfactory conversion of triglycerides to methyl esters (Table 1).…”

“…The chemical precipitation technique was used to prepare particles with homogeneous composition and narrow size distribution (Panneerselvam et al, 2011). A complete precipitation of Fe3O4 nanoparticles was achieved under alkaline condition while maintaining a molar ratio of Fe 2+ to Fe 3+ , 1:2, under inert condition.…”

Biodiesel is produced from edible/non-edible plants oil. However, alkaline transesterification of these oils makes the process challenging due to the presence of large amount of free fatty acids (FFA), which forms soap on reaction with alkali. Hence, it is necessary to reduce FFA present so that alkaline catalyzed transesterification can be carried out. In this work, biodiesel fuel was produced using diphenylamine functionalized magnetic mesoporous silica SBA-15 as catalyst for the esterification of free fatty acid (FFA) present in neem oil (NO) and its effect on esterification reaction was studied. Optimum catalyzed esterification was achieved using 1 g diphenylamine functionalized magnetic mesoporous silica SBA-15 as a solid base catalyst with a methanol to oil ratio of 9:1, at 60°C and reaction time of 1.25 h. During this process, FFA was converted into fatty acid methyl esters. The acid value of NO oil was reduced to 7.34 mg KOH/g from 52.45 mg KOH/g, accounting for 86% conversion efficiency. Consequently, this pretreatment reduces the overall complexity of the process and reduces the cost of producing biodiesel fuel. Pretreated NO was converted to biodiesel by a process of alkaline catalyzed transesterification using 1% KOH in methanol.

“…Among the physiochemical treatment methods available, adsorption becomes one of the applications that offers high efficiency, cost effective and easy handling process (Panneerselvam et al 2011). Previously, the adsorption was applied in dyes removal (AbdurRahman et al 2013;Chia et al 2013;Hashemian et al 2013;Malik 2004), metal ions (Ge et al 2012;Guo et al 2008;Yaacob & Samsudin 2007;Zainol et al 2014) and chemicals (Alam et al 2007;Vu et al 2015;Yao et al 2014).…”

“…In addition, they have an advantage as the speedy and easy removal of the adsorbent from the solution (by the help of magnetic field). Also, compounds can be removed from the magnetic particles and can be reused [9][10][11]. There are some studies (AC/TiO 2 , GAC/ZrO 2 , TiO 2 /sepiolite, and chitosan/ZnO) which prove that nanotechnological applications improved 2 Journal of Nanomaterials the adsorbent feature of the adsorbents, which are prepared in order to be used in adsorption practices [12][13][14][15].…”

The removal of Acid Red 114 (AR114) dye by adsorption process, using the magnetic nanoparticle (RHA-MNP) which is produced from rice husk ash burned at 300 ∘ C and the magnetic nanoparticle (MNP, Fe 3 O 4 ), was studied. Batch processes were used under different test parameters: pH (2, 4, 6, and 10) and without pH, initial dye concentration (20,40, 60, 80, and 100 mg/L), and contact time (0, 1, 5, 10, 15, 30, 45, 60, 90, and 150 min). Optimum conditions for AR114 removal were found to be at natural pH (pH without correction) for both adsorbents. Freundlich isotherm was found to be more consistent for MNP and Langmuir isotherm was found to be more consistent for RHA-MNP. The maximum adsorption capacities of MNP and RHA-MNP adsorbents for AR114 dye were equal to 111 mg/g. The kinetic experimental data fitted the pseudo-second-order model for both MNP and RHA-MNP. It can be concluded that RHA-MNP which is a waste could be used as low-cost adsorbent to remove AR114 from aqueous solution.
