“…23 Lastly, EES coating utilizes a fluoropolymer, which is the most chemically stable class of polymers known. 24 The ZES coating is an amorphous blend of 3 polymers without crystallinity, therefore ZES coating is softer than the EES coating. It is also less hydrophobic, and the water that it absorbs acts as a plasticizer, softening the coating further.…”

“…This would eventually stabilise thermodynamically and becomes less soluble due to the formation of hydroxyapatite (Ca 10 (PO 4 ) 6 (OH) 2 ) (Roques et al, 1991). As the calcium phosphate compounds ages and increases in size, the adsorption area decreases resulting in slower phosphorus adsorption rates although, it needs further investigation (Brady, 1990). …”

Rapid urbanisation has significantly increased the impervious surface along with increase in pollutants such as nutrients (nitrogen, phosphorus), sediments, oil, and hydrocarbon in stormwater. Their removal is important as they adversely affect the aquatic ecosystem and the environment. Thus, this study evaluated the performance of various adsorbent materials (red gum mulch, pine mulch, flyash, oyster shell, sawdust, clay, sand, zeolite, dolomite, alum and lime sludges) for the removal of phosphorus from synthetic stormwater. Among them, alum and lime sludges appeared to be the most effective in removing phosphorus. Further analysis showed that alum and lime sludges remove 99 and 90% phosphorus within 60 minutes from the synthetic stormwater. Therefore, this study demonstrates that the lime and alum sludges could be highly useful as a sustainable and cheap filter media for stormwater treatment systems that are enriched in phosphorus.

“…13,14) and the values of adsorption thermodynamic parameters are listed in Table 4. The negative value of DG o confirms the feasibility of the adsorption process and also indicates spontaneous adsorption of dyes on sulphonic acid group amine-converted GMAg-Teflon in the temperature range studied, which is usually the case for many adsorption systems consisting of oppositely charged adsorbate-adsorbent systems.…”

Mutual radiation grafting technique using Co-60 gamma radiation has been used to graft glycidylmethacrylate (GMA) to Teflon scrap. Cationic and anionic adsorbents were prepared from GMA-grafted Teflon scrap (GMA-g-Teflon) by converting epoxy ring into sulphonic acid and triamine groups by doing suitable chemical reactions at elevated temperatures. The converted grafted product was studied for its dye uptake properties from manufactured aqueous dye solution. Uptake of basic dyes namely, Basic red 29 (BR-29) and anionic dye namely, Remazol brilliant blue-1 (RB-1) was investigated. Langmuir and Freundlich adsorption models were used to analyze equilibrium adsorption, while kinetics of adsorption was analyzed using pseudo-first-order, pseudo-second-order models. The equilibrium adsorption of BR-29 and RB-1 was better explained by Langmuir adsorption model. Separation factor (R L ) was found to be in the range 0 \ R L \ 1, indicating favorable adsorption of basic and acidic dyes. Higher coefficient of determination (or regression) (r 2 ) and better agreement between q e,cal (calculated) and q e,exp (experimental) values were obtained for pseudo-second-order kinetic model.
