Delayed Luminescence

The decay kinetic models of delayed luminescence of beans have been examined, the effect of the shape of bean samples on the properties of delayed luminescence has been investigated. It is showed the delayed luminescence of beans mainly comes from the surface of beans and can’t reflect the whole information of beans. After beans being crushed, the component of beans can be mixed together. When luminescence, the components of beans powders are all irradiated, which can reflect the whole information of beans. The fitting degree of hyperbolic function is best.

Abstract Background Herbal materials are widely used as medicinal products, dietary supplements, food, and spices. With increased consumption, the safety, quality, and efficacy of herbal materials are becoming more relevant. The authenticity of herbal materials plays an important role in herbal quality control, and there is an urgent need to develop a simple, direct, objective, rapid, and inexpensive measurement tool for the identification of herbal materials for the purpose of quality control. Methods Delayed luminescence (DL) was used to measure authentic and counterfeit herbal materials. A hyperbolic function was used to extract four properties from the DL curves of the herbal materials. Statistical tools, including Student’s t test and Principal Component Analysis, were used to differentiate authentic and counterfeit herbal materials based on the DL properties. Results Our results showed that authentic and counterfeit herbal materials could be identified based on the DL properties as follows: (a) authentic versus counterfeit materials; (b) authentic versus adulterated materials; (c) authentic versus sulfur-fumigated materials; as well as (d) authentic versus dyed materials. Conclusion The simple, direct, rapid, and inexpensive measurements offered by DL potentially offer a novel technique for the identification of Chinese herbal materials. However, the establishment of a valid database will be the next step toward the possible application of this technique, which would contribute significantly to the development of a novel digital tool for the quality control of herbal materials.

This paper recommends maize stalk as a cheap natural ion exchanger. Ion exchange equilibrium was studied using thermodynamic and kinetic models. The results showed a high selectivity towards cationic species of antimony (III), molybdenum (VI), lead (II) and arsenium (III). Waste waters and sediments from tailing ponds samples were analysed.
