Abstract

Zn(II) is one of the heavy metals whose presence in large quantities can cause toxicity in water bodies so that it can cause death to organisms in the waters. The purpose of this study was to analyze the effect of red light color, contact time, and concentration on reducing Zn(II) levels in artificial wastewater using Tetraselmis chuii microalgae. The color of light applied was red with a wavelength of 620 – 760 nm. While the contact time varied was 30 minutes, 45 minutes, and 60 minutes with a concentration variation of 5 mg/L and 15 mg/L. The analysis conducted to identify the reduction of Zn(II) using Tetraselmis chuii microalgae is UV-Vis spectrophotometer analysis. The best Zn(II) removal efficiency was shown in the variation of contact time of 60 minutes, and initial concentration of 5 mg/L of 51.0805%.

Abstract

Direct release of inorganic compounds Cu (II) and Zn (II) into water bodies can disrupt ecosystems. Using microalgae biosorbent Tetraselmis chuii (T. chuii) is a promising approach for removing these metals from wastewater. This study investigated the effect of blue light on the absorption of Cu (II) and Zn (II) by analyzing the contact time and initial concentration. Statistical analysis (MANOVA) revealed differences in the biosorption process due to the contact time and Cu (II) concentration (P <0.05). The results showed that the most effective Cu (II) removal occurred with a 60-minute contact time at a concentration of 5 mg/L, achieving a 67.07% removal rate. Zn (II) removal was also efficient under blue light conditions with a 60-minute contact time at the same concentration, yielding a 56.23% removal rate. Additionally, this process led to a substantial reduction in microalgae T. chuii cell density, by 76% for Cu (II) and 89.2% for Zn(II). Characterization analyses using Fourier-transform infrared spectroscopy (FTIR) and scanning electron microscopy confirmed the presence of functional groups in T. chuii microalgae, which are crucial for the biosorption process. This study underscores the potential of microalgae as effective biosorbents for mitigating inorganic compound pollution in wastewater.
