Adsorpsi Ion Zn+2 Menggunakan Limbah Kulit Udang Teraktivasi Dengan Naoh

---

Shrimp waste is mostly made up of kit kits that can be converted into chitosan. The use of chitin and chitosan is primarily as a preservative and adsorbent. In this study, shrimp shrimp waste is used directly as an adsorbent on Zn+ 2 ions, with no history of shrimp become chitin or chitosan. The prawn shrimp waste in the early stages was subjected to a washing, drying, smoothing, sifting and activation process using a 0.5 M NaOH solution. The activated shrimp shell powder was then used as an adsorbent against Zn+ 2 ions by using particle size of adsorbent (pass 30, 60 And 100 mesh) and adsorbate concentration (20, 25 and 30 ppm) on the adsorption efficiency of Zn+ 2 ions. The fixed variables in this study are stirring speed (150 rpm), adsorbent weight (5 gram) and adsorbate volume (500 ml). The adsorption results were analyzed by atomic absorption spectroscopy. The results showed that shrimp shell waste activated with 0.5 M NaOH solution can be used as adsorbent to adsorb Zn+2 ion with the highest adsorption efficiency at 100 ppm particle size which is 98.93% while the highest adsorption occurs At 30 ppm adsorbat concentration With a particle size of 100 mesh of 29.5519 ppm. The activated adsorbent is more optimal in the Zn metal adsorption process compared to the non-activated adsorbent.
Keywords: adsorption, activation, adsorption efficiency, ion Zn +2, shrimp shell waste.
