Chitosan Performance of Shrimp Shells in The Biosorption Ion Metal of Cadmium, Lead and Nickel Based on Variations Ph Interaction

Abstract

The widespread use of chitosan waste shrimp extract to reduce the toxicity of certain heavy metals can reduce the escalation of the potential threat of environmental pollution. First) shrimp shell processing is intensively done so it is not wasted freely into the environment, second) toxicity of heavy metals decreased significantly with the application of chitosan adsorption method to heavy metals conducted in wider society. Bioadsorption method of heavy metals of ions Cadmium, Lead and Nickel using chitosan begins with insulation chitosan shell chitosan. The isolated chitosan was characterized. The performance of chitosan adsorption the three types of heavy metal tests was determined by chitosan interaction of each metal at varying pH interactions (pH 2-8). Interaction media conditions: 100 mL medium volume, total chitosan used 1 g, contact time 60 min, the heavy metal concentration of 200 μg/g cadmium ion test, Lead ions and Nickel respectively 100 μg/g. Determination of absorbance using Atomic Absorption Spectrophotometer. The measured value of the adsorbent is converted to the maximum chitosan adsorption concentration value. The adsorption capacity of metallic chitosan complex, maximum was achieved for metal Cd 2+ at pH 2 of 198.2051 μg/g (99.05 %), metal Pb 2+ at pH 4 of 59.3341 μg/g (59.33 %) and metals Ni 2+ at pH 7 of 45.1334 μg/g (45.13 %). This result indicates that pH value of interaction media has an effect on chitosan adsorption to heavy metal test with Cd 2+ ˃ ˃ Pb 2+ ˃ Ni 2+ sequence

Crustacean Waste Shells as Adsorption Materials for Heavy Metals in an Aqueous Solution

“…A dosage range of 0.5-1.5g, a 98 % of removal pesticide was found. This was attributable to the fact that with greater doses of sorbents 0.5 g, the active sites available on the nanocomposite were diminishing (Rahman, 2012;Marzuki, 2019). The surface area that was fully active increases as the composite dosage is increased (Ponce, 2017;Rana 2009).…”

Investigation of Global Trends of Pollutants in Marine Ecosystems around Barrang Caddi Island, Spermonde Archipelago Cluster: An Ecological Approach

“…GTP are pollutants that are very difficult to decompose through biodegradation, bioadsorption, and bioreduction methods, including destruction methods. The treatment approach using bioremediation methods for global trending pollutants is challenging to conduct on a large scale with a technological approach [49,50]. Bioremediation microorganisms can be used, where the natural aid of biological materials, such as bio-adsorbent plants, is employed.…”

Temporal and Spatial Analysis of Coastal Water Quality to Support Application of Witheleg Shrimp, <em>Litopenaeus vannamei</em> Intensive Pond Technology

“…Whiteleg shrimp is still strategic support for achieving the national shrimp production target. Whiteleg shrimp culture technology in ponds consists of traditional, traditional plus, semi-intensive, intensive, and super-intensive [8][9][10].…”

“…Intensification of whiteleg shrimp culture uses more efficient land and higher productivity [8,9,[11][12][13] and reduces land use costs by more than 90%/kg shrimp [11].…”

“…Efforts to produce more shrimp in shrimp culture with intensive technology, pond farmers can increase production to meet the needs of shrimp demand without putting pressure and burden on the contribution of waste to natural resources [12,15]. On the other hand, the intensification of whiteleg shrimp culture ponds can negatively impact polluting waste in the aquatic environment in coastal areas [8,11,[16][17][18]. Waste from whiteleg shrimp ponds can come from shrimp feed and faeces.…”
