“…Furthermore, the removal of catechol from the effluent was evaluated using a chemometric approach [ 41 ], and the removal of catechol in the simulated effluent attained 99.4% removal, indicating that ABC carbon material is efficient for the removal of catechol from simulated industrial effluents.…”

This work proposes a facile methodology for producing porous biochar material (ABC) from açaí kernel residue, produced by chemical impregnation with ZnCl2 (1:1) and pyrolysis at 650.0 °C. The characterization was achieved using several techniques, and the biochar material was employed as an adsorbent to remove catechol. The results show that ABC carbon has hydrophilic properties. The specific surface area and total pore volume are 1315 m2·g−1 and 0.7038 cm3·g−1, respectively. FTIR revealed the presence of oxygenated groups, which can influence catechol adsorption. The TGA/DTG indicated that the sample is thermally stable even at 580 °C. Adsorption studies showed that equilibrium was achieved in <50 min and the Avrami kinetic model best fits the experimental data, while Freundlich was observed to be the best-fitted isotherm model. Catechol adsorption on ABC biochar is governed by van der Waals forces and microporous and mesoporous filling mechanisms. The Qmax is 339.5 mg·g−1 (40 °C) with 98.36% removal of simulated effluent, showing that açaí kernel is excellent biomass to prepare good biochar that can be efficiently used to treat real industrial effluents.

“…Correlation analysis and PCA/FA techniques had been highlight by Prasanna et al [12] in the study of heavy metal pollution index and river water quality of Miri city (Malaysia), which is important to determine the potential sources of river water contamination. Moreover, these techniques had been widely used in other studies to classify and clustered the monitored sampling stations as well as to interpret the latent source of river water pollution [13][14][15][16]. Based on above literature studies, majority research using correlation analysis to verify relationships between the studied parameter of river water quality; while CA technique is to cluster the monitored stations that have similar characteristics based on water quality parameters; as well as FA/PCA technique is to define the source of water pollutants in the river.…”

This study aims to determine the spatial and temporal variation on water quality and to identify the main pollutant sources in Melaka River basin. Based on nine monitored sampling stations, twenty variables of water quality data were used in this study for year 2016. Multivariate statistical techniques include Pearson correlation analysis, principal component analysis (PCA), and cluster analysis (CA) is applied to analyze the water quality data. The results indicate water quality in several stations were over the limit of Malaysian water standards. PCA used to compute the pattern within the analysis of water samples, and recognized on five factors in dry and wet season with the total of variation is 73.22% and 76.58% in the river water data respectively. These suggest concentrations of pollutant sources are associated with point source (municipal and domestic waste, sewage treatment plants, and industrial effluents), non-point source (agriculture, livestock), and natural process (weathering of soil and rock). CA explained rainfalls and other sources including surface runoff and wastewater discharges which become main contamination indicator to relatively affect surface water quality through spatial and seasonal variation. Overall, municipal wastes and industrial effluents required serious treatment due to potential impact on water and potential hazard to consumer's health. Therefore, this study suggests anthropogenic activities in Melaka River basin required wise management.
