“…Although the presented evidence is not sufficient for a concrete explanation, we hypothesize that a similar sequestration mechanism described in literature is displayed in these results [22][23][24][25]28], have revealed that the chemical structure of MOP suggests that the tail of this protein does not display any coagulation capabilities. This tail may have been the part of the MOP that attached to the surface of RHA and allowed MOP to be immobilized.…”

“…In the present work, we test the extent to which functionalization of RHA by Moringaoleifera proteins (MOP) can effectively enhance the adsorptive capacity of bare RHA. We have previously presented that moringa-functionalization can be an effective way to enhance the adsorptive capability of RHA to various contaminants in water [22][23][24][25]. We also apply this methodology to assess the extent of amoxicillin removal using the moringa-functionalized RHA.…”

Lack of stringent policies requiring water treatment facilities to combat occurrence of residual antibiotics in effluents critically impairs the resiliency of low-income communities to drug-resistant pathogens. In an attempt to mitigate the effects of residual drugs in aqueous media, we investigate the extent to which rice husk ash (RHA) functionalized by Moringaoleifera protein (MOP) sequestrates amoxicillin in solution. A semi-factorial design was implemented to evaluate the influence of initial amoxicillin concentration, initial MOP functionalized RHA dosage, and contact time on the removal on amoxicillin in water. Results of our experiments have shown that MOP functionalization enhanced RHA by doubling its rate to sequestrate amoxicillin molecules in solution. This strongly indicated that MOP adhered on the surface of RHA significantly improved its capacity to remove amoxicillin contamination in aqueous solution. Statistical analysis employed further supported our results by implying a significant difference between the performance of MOP-functionalized and bare RHA. In conclusion, our results strongly suggest that MOP functionalization can be a potential practical solution to alleviate the vulnerability of communities to emerging antibiotic pollution.

“…However, a concern in this matter is their organic carbon content which if left suspended in the treated water acts as food for the residual E. Coli. This was overcome by adsorbing moringa proteins on RHA which showed reduced total organic compound by over 99.7% compared to when used in a standalone manner [45]. Absorption characteristics of modified sodium alginate derived from biological source added at various concentration into RHA-silica was investigated.…”

Asian countries rely massively on rice to feed and sustain its massive population. For long the staple food has provided nourishment to the masses and the classes. Rice is grown in large quantities in Asian countries. A by-product of its cultivation is its husk. The husk of the rice grain is mainly utilized as a fuel for the boilers in the rice mills. The uncontrolled burnt rice husk referred to as rice husk ash consists majorly of silica. silica is used in a wide variety of commercial and industrial applications. Use of rice husk ash in various products serves to reduce the pollution caused by its pileup in localities especially close to the rice mills. More sustainable and an affordable source of Si would benefit the society rather than disposing rice husk ash in the fields and landfills. This brief review provides insights into the synthesis, applications, and properties of rice husk ash incorporated products either directly in the as received conditions or under modified conditions.

The absence of comprehensive programs in regulating release of lead to the environment in growing cities situated in developing countries results to widespread intrusion of lead bioaccumulation in their primary sources of food. As a result, a significant increase in lead related diseases continually grows in many low income regions. In an attempt to provide a means of minimizing lead bioaccumulation, we test the extent to which Moringaoleifera seeds (MOS) removes lead (II) ions in aqueous solution. A box-behnken experimental design was used to obtain the optimal conditions in the lead (II) removal process. MOS dosage, initial lead (II) concentration, and pH were found to have significant effects on the percent removal of lead (II) in solution. Actual values of these independent variables were chosen on the basis of preliminary experimental results. Optimum conditions were found to be: MOS dosage 10.0 g/L, initial lead (II) concentration 20.0 ppm, and pH at 5.5. Lead removal using MOS was also performed at optimal conditions. In conclusion, a high lead (II) removal using MOS strongly suggests its potential to be used as a means of treating liquids highly contaminated with lead.
