Assessment on the removal of dimethyl phthalate from aqueous phase using a hydrophilic hyper-cross-linked polymer resin NDA-702

Occurrence, fate and effects of Di (2-ethylhexyl) phthalate in wastewater treatment plants: A review

“…In a recent study conducted in seventeen municipal WWTPs (Austria), it has been shown that less than 17% of DEHP were bio-transformed, while 78e81% were adsorbed on sludge (Clara et al, 2010). According to Zhang et al (2007), AS process required longer hydraulic retention time to render phthalates harmless and microorganisms can hardly degrade them from aqueous solution. High solid retention time (SRT) allowed developing specific microorganisms capable of degrading refractory pollutants.…”

Degradation of dimethyl carboxylic phthalate ester by Burkholderia cepacia DA2 isolated from marine sediment of South China Sea

“…Although coagulation by flocculation is useful for the removal of organic micropollutants and its removal mechanism has been reported (Thebault et al 1981), coagulation by ferric chloride was not very effective and efficient. Adsorptive removal by activated carbon, b-cyclodextrin, macroreticular resin, and diatomite was effective (Adhoum and Monser 2004;Murai et al 1998;Zhang et al 2007), but these methods could not eliminate the chemicals from the environment completely.…”

Equilibrium and heat of adsorption of diethyl phthalate on heterogeneous adsorbents

“…To obtain larger adsorption capacity and better affinity for a specific organic pollutant, chemical modification of ordinary polymeric resins is often adopted by grafting some special functional groups onto the matrix of the resins [23,24]. In particular, the introduction of hydrogen-bonding acceptors/donors as functional groups onto the matrices of the resins will aid in the development of a series of new-style hydrogen-bonding adsorbents for completely removing specific organic pollutants from wastewater.…”
