Recent Findings from National Sun Yat Sen University Provides New Insights into Carboxylic Acids (Monitoring and removal of residual phthalate esters and pharmaceuticals in the drinking water of Kaohsiung City, Taiwan)

By a News Reporter-Staff News Editor at China Weekly News -- Investigators publish new report on Carboxylic Acids. According to news originating from Kaohsiung, Taiwan, by VerticalNews correspondents, research stated, "This study monitored the occurrence and removal efficiencies of 8 phthalate esters (PAEs) and 13 pharmaceuticals present in the drinking water of Kaohsiung City, Taiwan. The simultaneous electrocoagulation and electrofiltration (EC/EF) process was used to remove the contaminants."

Our news journalists obtained a quote from the research from National Sun Yat Sen University, "To this end, a monitoring program was conducted and a novel laboratory-prepared tubular carbon nanofiber/carbon/alumina composite membrane (TCCACM) was incorporated into the EC/EF treatment module (collectively designated as 'TCCACM-EC/EF treatment module') to remove the abovementioned compounds from water samples. The monitoring results showed that the concentrations of PAEs were lower in water samples from drinking fountains as compared with tap water samples. No significant differences were found between the concentrations of pharmaceuticals in the two types of water samples. Under optimal operating conditions, the TCCACM-EC/EF treatment module yielded the lowest residual concentrations, ranging from not detected (ND) to 52 ng/L for PAEs and pharmaceuticals of concern in the tap water samples. Moreover, the performance of the TCCACM-EC/EF treatment module is comparable with a series of treatment units employed for the drinking fountain water treatment system."

According to the news editors, the research concluded: "The relevant removal mechanisms involved in the TCCACM-EC/EF treatment module were also discussed in this work."
