Abstract

Urbanization, industrialization and population growth are the three prime factors causing the deduction to groundwater quality for drinking as well as for domestic purposes. Other than natural calamities, anthropogenic calamities arising of human casualties are prime factor to destroy the healthy ecological cycle. Unplanned disposal of dye/pigments, pharmaceutical chiral wastes, heavy metals, and other chronic wastes have posed threat towards health implications of mankind across globe. Water detoxification from chronic wastes can be controlled with material showing efficiency, sustainability, people friendly, cost effective, safer disposal ways, recyclable and less labour for maintenance. Taking into account the concern related to water pollution the idea was implemented to grow water immiscible material. The idea for new material model is highlighted in the thesis entitled “Design, Synthesis and Application Demonstration of 3D Crosslinked Polymer Network”. The thesis reveals the unique pathway to growth of novel material presented as porous organic polymer abbreviated as POP to water detoxification. Such POP model can be used either by direct or indirect pathway to water purification. Here the direct mode corresponds to adsorption and chelation of wastes whereas the indirect mode corresponds to catalysis where the waste decomposition occurs. The condensation and addition polymerization was jointly made operational to grow neutral and ionic POP′s. The PAH functionalized POP showing response to emission tunability can show potential to catalyzing the reaction in presence of catalyst. The click polymerization technique was invoked for the growth of stereogenic/chiral POP which can be expected to show response for selective removal of chiral wastes such as pharmaceutical drugs, pesticides, etc. The click hydrothiolation could show efficient and controlled input of magnetic constituents like cobalt. Such magnets can play crucial role to catalysis, act as seismic dampers, act as prosthetic tool and can influence removal of magnetic wastes. POP′s were also engineered for monitoring both organic dye and inorganic wastes such as rhodamine B, mercury ion and fluoride ion form water.
