The metal remittance in this review is Fe metal, since Fe is one of the metals that is generally contained in water. Whenever devoured water containing Fe that surpasses the limit, it will be awful for wellbeing. The purpose for this research was to portray the biosorbent of snail shell powder and to test the presentation of the biosorbent in the retention of substantial metal iron (Fe). From the aftereffects of the FTIR test, it is assessed that there has been an adjustment of chitin to chitosan. The chitosan spectra acquired showed the presence of a retention band at a wave number of 3066 cm-1 because of the extending vibration of the - Goodness bunch. while for the portrayal utilizing SEM, the molecule size of the biosorbent has different sizes, to be specific with a size scope of 2.16 - 3.44 m to 2.54 - 12.12µm. The development of a coral-like surface is the most definitive factor in the partition of the weighty metal retention interaction of Fe. The computation of the viability esteem showed that the adequacy of snail shell powder in engrossing 10 ppm Fe metal was at a mass of 20 g with a mixing season of 30 minutes, which was 99.2%.

“…Ngatidjo et al (2011) also utilized silica from amine-modified rice husks as an adsorbent for copper metal ions. In addition, research on silica from rice husks was carried out by Valentine et al (2019), who produced chitosan membranes by adding rice husk ash silica as an additive to a casting solution to reduce Cu heavy metal.…”

The influence of rice types on the purification of rice husk ash was investigated by extracting silica and purifying it with a 12% NaOH solution, followed by the coprecipitation technique. Rice husk samples were from Mbay (Nagekeo Regency) with two different varieties, Ciherang and Inpari 42, and from Soa (Ngada Regency) with Ciherang variety. The silica produced in this research was characterized using UV Vis spectrophotometry to obtain the surface area value. The surface acidity value was calculated using the acidbase titration method. Using XRF, the purity of silica was determined. Ciherang Mbay, Ciherang Soa, and Inpari Mbay had surface area values of 18.397 m2/gram, 18.347 m 2 /gram, and 18.491 m 2 /gram, respectively. The surface acidity value of the three samples was 45.1 mmol/gram, 45.5 mmol/gram, and 44.7 mmol/gram, respectively. The purity of silica from rice husk ash Ciherang Mbay, Ciherang Soa, and Inpari Mbay samples based on XRF was 98.6%, 98.3%, dan 99.2%, respectively. Silica with the highest purity (Inpari Mbay variety) was applied as an adsorbent in the adsorption process of manganese (Mn(II)) metal ion with an adsorption capacity of 212.76 µmol/gram and adsorption energy of 38.165 kJ/mol through chemical adsorption.
