ABSTRACT
This study aimed to determine the phytochemical components of the ethanolic seed extract of Ziziphus talanai (Blanco) Merr. The phytochemical screening revealed the presence of flavonoids, anthraquinones, alkaloids, phenol, tannins, flavonoids, and essential oils. Moreover, the study aimed to determine the potential of Z. talanai as a coagulant-flocculant for wastewater treatment. Different dosages from 1.0 g, 2.0 g, 3.0 g, 4.0 g, 5.0 g, 6.0 g, 7.0 g, 8.0 g, 9.0 g, and 10 g of alum and Z. talanai were tested for their significant difference in terms of their turbidity and pH in kaolinite-synthetic wastewater. One-way Analysis of Variance (ANOVA) was used to measure the significant difference (Ξ± = 0.05) between turbidity and pH. Scheffe’s method was used as the post hoc test to identify possible pairs. Results for alum showed no significant difference in turbidity as the F computed value of 1.03 was less than the F tabular value of 2.85 at a 0.05 level of significance. Additionally, no significant differences were also observed in the pH of alum as the pH for different dosages has the same value of pH 4. Results revealed that overdosage of alum caused the charge reversal of colloids which prompted no significant difference. On the other hand, Z. talanai showed a significant difference in turbidity as the F computed value of 33.33 was greater than the F tabular value of 2.85 at a 0.05 level of significance. In addition to that, pH under 2. talanai also showed a significant difference as the F computed value of 2.93 was a bit greater than the F tabular value of 2.85 at a 0.05 level of significance. Results revealed that the presence of phenolic compounds aided the significant results for turbidity while neutralization of charges increased the value of pH.
