“…The seeds were used in the determination of silver in water [20], inorganic arsenic in natural waters [21], cadmium and zinc in alcohol fuel [22,23] and lead in beer samples [13]. Its husks were used in the selective extraction of chromium in water [24], in the copper determination in gasoline samples [25], in zinc determination in cachaça, and in the determination of lead in chicken feed [27].…”

This chapter provides an overview and discusses analytical strategies for metallic ions determination using solid phase extraction. Solid phase extraction (SPE) is a much-used technique for extraction and/or concentration of complex samples, so that the analytes present in low concentration were detected mainly using chromatographic methods. However, in recent years, this technique has been widely used in the development of methodologies for metallic ions determination in the deferential samples. This technique shows simplicity and rapidity comparing with other conventional techniques, liquidliquid extraction, cloud point extraction and others. Solid phase extraction procedures become even more interesting when commercial adsorbents are exchanged for others with higher adsorptive capacity, selectivity, flexibility, economy and low environmental impacts. For this purpose, some inorganic, organic and several natural adsorbents are used. New approaches to obtain adsorbent materials from natural sources such as fungi, bacteria, industrial residues and composting materials have received attention. These materials have been used in the development of analytical methods with varied proposals, such as preconcentration or speciation of metal ions.

Moringa oleifera is an important tropical food plant that seems to have great nutritional, therapeutic, industrial, agricultural, and socioeconomic value. Dietary consumption of its parts and preparations is encouraged by several organizations, health food enthusiasts, and other specialists as a strategy of personal health preservation and self-medication in the treatment of various diseases. Studies extoling its ability to mitigate various degenerative ailments now exist in both the scientific and the popular literature. At face value, and considering the volume of reports available, much of this enthusiasm seems to be indeed justified. However, it is imperative to distinguish rigorous scientific evidence from anecdote. To achieve this, relevant experimental and review articles were sought and read critically to identify recent patterns and trends on this subject matter. Studies on the medicinal and functional properties of M. oleifera are available from various parts of the world, especially developing regions. Attempts have been made to parse the contemporary scientific data available supporting the claims regarding the phytochemical, nutritive, medicinal, environmental, agricultural, and socioeconomic capabilities of this plant. Studies reviewed provide compelling, albeit preliminary experimental evidence of therapeutic potential of the plant. It is important that M. oleifera products and preparations be properly chemically characterized and standardized before being administered.

“…Recently, the need for new technologies involving the removal of toxic metals from waste water has directed attention to biosorption due to low cost, free availability, high adsorption, possible reuse and flexible operation (Yang et al, 2009;Volesky, 2003;Park et al, 2010;Safa and Bhatti, 2011). Moringa oleifera husks have recently been used as biosorbents for determination of lead in chicken feed (Oliveira et al, 2017). However, a comparative analysis of different M. oleifera parts has not been done side-by-side.…”

This research article presents a comparative study of the adsorption properties of Moringa oleifera biomass using Pb 2+ ions as test analyte. The investigated parameters which affected the adsorption process were the effect of pH, initial concentration, adsorbent dose, contact time, and temperature. The comparison of adsorption process was evaluated in the pH range of 3 to 8, concentration range from 5 to 20 ppm, temperature varied from 25 to 80°C, variation of contact time from 15 to 80 min, and dose of the adsorbent from 0.3 to 1.2 g. The results obtained showed that a high adsorbent dose is required for high adsorption capacity. The pH of 7 was most effective with temperature set at 25°C and contact time of 60 min. The Temkin, Dubunin-Radushkevich, Langmuir and Freundlich isotherms were applied and fitted well to the data and values of the parameters of these isotherm equations were calculated. The Langmuir isotherm proved to be the overall best isotherm. The adsorbent surface functional groups were identified with Fourier Transform Infrared (FTIR) spectroscopy. The maximum adsorption capacity obtained was 98% for seed, 96% for blended, 94% for pods, and 92% for leaves. Better thermodynamic and kinetic properties were obtained with the seeds and the blended samples. In total, these results indicate that the blended moringa biosobent can be employed as a low-cost biosorbent for the removal of lead ions from water.
