Nano-phytoremediation Application for Water Contamination
Nanotechnology and phytoremediation both have potential for water purification by removal of contaminants from water. Removal efficiency can be enhanced by combining both the technologies. Both technologies are complementary to each other. Nano-phytoremediation has more cumulative effect than the impact of individual technology. This chapter has provided in-depth overview regarding the progress in the use of nano-phytoremediation application for water purification. This paper highlights the contamination status in Indian context. Through the lens of bibliometric analysis, the research publications have been mapped in the field by different countries, and the analysis is further extended to know the existing technology based on nano-phytoremediation. Comprehensive information regarding international patent classes related to nano-phytoremediation through various patent databases has been explored, and the available patents in this field has been summarized, particularly used only for water contamination removal. Results are discussed in details in this nascent field publication and patent the previous studies. Patent analysis brought about the knowledge of potential technologies available in different nano-phytoremediation techniques. A bibliometric approach is used to analyze the relevant publications in this area to map countries of this emerging area.
