“…The highest chromium removal percentage (99.75%) by dry alga, Chlorella vulgaris, was obtained using 60 mg/50 mL solutions (1.2 g/L) 70 . Gandhi et al 72 demonstrated that the highest percentage uptake of chromium was obtained with 8.0 g algae as biosorbent. The highest chromium removal (83.55%) was obtained with 0.6 g/L Sargassum sp.…”

A large number of industries use heavy metal cations to fix dyes in fabrication processes. Malachite green (MG) is used in many factories and in aquaculture production to treat parasites, and it has genotoxic and carcinogenic effects. Chromium is used to fix the dyes and it is a global toxic heavy metal. Face centered central composite design (FCCCD) has been used to determine the most significant factors for enhanced simultaneous removal of MG and chromium ions from aqueous solutions using marine green alga Enteromorpha intestinalis biomass collected from Jeddah beach. The dry biomass of E. intestinalis samples were also examined using SEM and FTIR before and after MG and chromium biosoptions. The predicted results indicated that 4.3 g/L E. intestinalis biomass was simultaneously removed 99.63% of MG and 93.38% of chromium from aqueous solution using a MG concentration of 7.97 mg/L, the chromium concentration of 192.45 mg/L, pH 9.92, the contact time was 38.5 min with an agitation of 200 rpm. FTIR and SEM proved the change in characteristics of algal biomass after treatments. The dry biomass of E. intestinalis has the capacity to remove MG and chromium from aquatic effluents in a feasible and efficient manner.

“…Penyerapan ion Cr(VI) oleh adsorben dari rumput laut (Fucus vesiculosus) dibuktikan dengan analisis FT-IR terdapat gugus hidroksil (-OH) dan gugus amino yang berkurang setelah adsorbsi yang menyebabkan ion Cr(VI) terikat pada permukaan adsorben (Cobas, Saronman, & Pazos, 2014). Salah satu pemanfaatan limbah biomassa dijadikan sebagai adsorben adalah adsorben dari cangkang Arenga pinnata merr untuk logam Cr(III) dan Cr(VI) (Zein, Arrisujaya, Hidayat, Elfia, Nazarudin, & Munaf., 2014), Adsorben dari limbah sekam dan jerami padi Singha, Naiya, Bhattacharya, & Das, 2011;Kumar, Arya, Singh, & Vats, 2017), akar eceng gondok (Singha et al, 2011); tempurung kelapa (Singha et al, 2011), kulit kayu pohon mangga, batu bata, batu kapur, bubuk biji pepaya dan Alga (Gandhi, Sirisha, & Sekhar, 2013) dapat dimanfaatkan untuk mengurangi cemaran ion logam Cr(VI), adsorben dari biji alpukat untuk logam Cu(II), Pb(II) dan Cd(II) (Wanja, Murungi, Wanjau & Hassanali, 2015).…”

Velvet Apple Fruit Seeds (Diospyros blancoi) as Biosorbent of Cr(III) Velvet Apple Fruit (Diospyros blancoi) has not been explored more in Indonesia. The purpose of research was to explore the use of Velvet Apple Fruit seeds as adsobent of Cr(III) in waste. Biosorbent of velvet apple fruit seeds in removing Cr (III) metal ions has been investigated using batch method. Several parameters were used to determine absorption optimum conditions such as solution pH, contact time and biosorbent dosage. Langmuir, Freundlich and Temkin isotherm models were used in determining biosorption equilibrium. FTIR and SEM-EDX were used to characterize the velvet apple fruit seeds biosorbent. The equilibrium adsorption isotherms showed the velvet apple fruit seeds biosorbent had a maximum adsorption capacity of 5.592 mg/g. The adsorption efficiency of Cr (III) ion by velvet apple fruit seeds was 81.78%. The results showed that velvet apple fruit seeds potentially as an alternative low-cost biosorbent for removing heavy metal ions in solution.Keywords: biosorption, heavy metals, alternative biosorbent, waste water treatmentABSTRAK Buah bisbul di Indonesia belum tereksplor dengan baik potensinya. Tujuan penelitian adalah untuk megetahui potensi biji buah Bisbul sebagai adsorben logam Cr(III) pada limbah. Biosorben biji buah bisbul (Diospyros blancoi) dalam menyerap ion logam Cr(III) telah diteliti dengan menggunakan metode batch. Beberapa parameter digunakan untuk menentukan kondisi optimum penyerapan seperti pH larutan, waktu kontak dan dosis biosorben. Model isoterm Langmuir, Freundlich dan Temkin dipakai dalam menentukan kesetimbangan biosorpsi. FTIR dan SEM-EDX digunakan dalam mengkarakterisasi biosorben biji buah bisbul. Isoterm adsorpsi kesetimbangan menunjukkan biosorben biji buah bisbul mempunyai kapasitas adsorpsi maksimum 5,592 mg/g. Efisiensi penyerapan ion Cr(III) oleh biji buah bisbul mencapai 81,78%. Hasil penelitian menunjukkan bahwa biji buah bisbul berpotensi sebagai alternatif biosorben murah dalam menghilangkan ion logam berat dalam larutan.Kata kunci: biosorpsi, logam berat, alternatif biosorben, pengolahan air limbah

The present study, conducted in 2018, aimed to treat landfill leachate using the Ceratophyllum demersum plant and convert the wastewater nutrients into protein-rich biomass. The experiment was carried out for 45 days in an enriched medium with ½ Hoagland nutrient solution. Regarding the experimental setups, C. demersum cultivation was performed in four different dilution ratios (100%, 75%, 50%, and 25%) in the landfill leachate. The changes in the chemical properties of the wastewater (pH, NO₄⁻-N, NO₂⁻-N, NO₃⁻-N, and o-PO₄³⁻) were measured. The values in the leachate and after treatment were measured as follows: NH₄⁺-N ranged from 18.03 to 476.2 mg/L, NO₃⁻-N ranged from 5.0 to 33.98 mg/L, NO₂⁻-N ranged from 1.49 to 7.06 mg/L, and PO₄³⁻-P ranged from 27.99 to 145.4 mg/L. The protein yield (CP prot) in the experimental groups at the end of the 45-day study was as follows: T1 = 20.90%, T2 = 36.68 %, T3 = 41.78%, T4 = 47.43% and T5c = 49.56%. These results demonstrate that aquatic plants can be utilized in wastewater treatment and as animal feed due to their high protein yield. In my research, a completely nature-friendly treatment technique was used to reduce water pollution without using any chemicals.
