background silver has been used from ancient times by humans, and recently nanoparticles of silver have been used in many aspects of human life including as a potent antibacterial agent. objectives in the current study a completely green method to prepare silver nanoparticles is reported. two types of starches (potato and corn starches) were used to produce and stabilize silver nanoparticles. a...

By applying concept and principles of green chemistry into different technological processes, green technologies are developed. The environmental and economic benefits of “green” approach is achieved through several directions, such as the use of renewable raw materials, creation of economic efficiency, the use of alternative reaction conditions, as well as the application of non-conventional s...

The technology of phytoremediation is cost effective and ecologically friendly in which plant utilizes its natural abilities to restore environment. In nature there are a number of plants existing with innate mechanisms for removing heavy metals from soil, air and water as a survival strategy.  Among several subsets of phytoremediation, the widely studied strategies are (a) phytoextraction (b) ...

background: neptunia oleracea or ‘water mimosa’ has a phytoremediation ability which is rarely being assessed. this plant also can be eaten as raw or cooked and but brought such concern on its safety for human consumption. the objective of this study was to assess the phytoremediation ability of water mimosa and its safety for human consumption. methods: water mimosa was treated with pb, cu and...
