FTIR SPECTRA OF LIFE BIOMASS OF NANNOCHLOROPSIS SPECIES AFTER PHYCODEGRADATION OF PHTHALATE ESTERS
Abstract
ABSTRACT
Urbanization has increased the discharge of phthalate esters to atmospheric and aquatic
environments, and the use of agricultural plastics has exacerbated soil contamination by
phthalate esters in rural areas. Aerobic biodegradation is the primary manner of phthalate ester
mineralization in the environment, and this process has been widely studied. Phthalate esters can
be removed during wastewater treatment processes. The combination of different wastewater
treatment technologies showed greater efficiency in the removal of phthalate esters than
individual treatment steps. The aim of this study is to analyze the chemical components formed
after the degradation of phthalate ester. The infrared spectrum of dried algal biomass and its
residue were recorded by Shimadzu Fourier Transform Infrared (FTIR) spectroscopy. Both kinds
of samples were mixed with potassium bromide (KBr) powder, and then pressed into tablets
before measurement. Samples were scanned from 400 to 4,000/cm. The potential and properties
of N. oculata biomass for futuristic renewable fuel have been studied. With traditionally natural
and low-cost nutrient cultivation, this algae species grows rapidly. The physicochemical
properties of this biomass also indicated that it is feasible as biofuel feedstock, except for its high
content of inorganic components, which need special attention.
