Producing drinking water from polluted water is expensive; thus, the fabrication of environmentally‐friendly and cost‐effective materials to treat polluted water is vital. A strategy involving the exploitation of waste resources to mitigate their impact on the environment has attracted special attention. This strategy is achievable by, among other things, developing materials including ceramic filters. In this study, natural clay, and macadamia nutshell powder were used to fabricate ceramic filters to remove methyl orange (MO), chromium (Cr), and lead (Pb) from aqueous solutions. The physicochemical characteristics of the fabricated filters were carried out and their ability to remove the pollutants was investigated. The filter with 20 wt% macadamia nutshell powder (M2) removed 92 %, 62 %, and 29 % of MO, Pb (II), and Cr (III), respectively. This was attributable to the high porosity of the filter as demonstrated by Brunauer‐Emmett‐Teller analysis. Furthermore, there was an increase on the removal of Cr (29.71 % to 84.5 %) in the presence of other competing co‐metals, however, a drop in Pb removed was observed (62.99 % to 38.67 %). Turbidity removal of up to 97.2 % was achieved using the M2 filter. The reported filter fabrication approach is facile, easy to replicate without special training, and environmentally friendly.

This work concerns the coacervate extraction of industrial dye, namely Acid Green 9 (AG-9) from aqueous solution by nonionic surfactant Lutensol AO7 and TX-114 (readily biodegradable). Binary water/surfactant and pseudo-binary phase diagrams were plotted. The extraction results as a function of wt% of the surfactant and temperature are expressed by: percentage of solute extracted, E%, residual concentrations of solute and surfactant in the dilute phase (X s,w and X t,w respectively) and volume fraction of coacervate at equilibrium (Фc). For each parameter, whose values are determined by a design of experiments, these results are subjected to empirical smoothing in three dimensionsusing response surface methodology (RSM). The aim of this study is to find out the best compromise between E % and Фc. Under optimal conditions, the extraction extent of AG-9 reaches 98 % and 96 % using TX-114 and Lutensol AO7, respectively. The effect of Na2SO4 and CTAB addition is also studied. Finally, the possibility of recycling the surfactant is proved.
