“…Chloroacetylation reaction supported an excellent yield of 85 % and chlorine atom content of ∼ 22 % as calculated via iodometric titration. [36] Basically, the chloroacetyl-chitosan provides an active site to tether tannin covalently to chitosan backbone at chloro atom and consequently results plentiful Ar-OH groups for the adsorption applications. The detailed reaction scheme for multi-functional support is presented in Scheme 1.…”

The multi‐functional, green and environmental acceptable adsorbents were synthesized from activated chitosan for fluoride ions via mild‐strategies. Chloroacetylation reaction was performed to integrate an active group to the chitosan structural unit. Subsequently, the integrated active group was derivatized with tannin acid, an environmental‐friendly natural polyphenol via a simple reaction. The synthesized products were evaluated for their structures via FTIR, 1H‐NMR, UV, SEM‐EDS, elemental mapping, BET surface analysis, and XPS. The capability of the synthesized green products was appraised for fluoride ions sorption in circumneutral conditions. The results confirmed the maximum sorption capability of ≥97 % even at trace level and also proved remarkable results in competition with competitive ions. The equilibrium sorption data supported the maximum adsorption capacity of 28.57 mg g−1 by the Langmuir model within 60 min at pH 7.0, which is nearly analogous to the experimental data of 22.02 mg g−1 at 10 ppm. Therefore, in conclusion, the proposed green adsorbent is economical, and is even appropriate at almost neutral pH, which designates its applicability for treating drinking water.

Opportunistic Networks are pure wireless networks in which no direct communication is present between nodes In OPPNET no base station is used for further communication. Data transmission takes place through intermediate nodes. These intermediate nodes uses store-carry-forward model for data transmission. In opportunistic network numbers of routing protocols are presented. Routing protocols are used for data transmission in network. In this paper first introduce Opportunistic network in detail then performs a comparative analysis on different routing protocols.
