In the meat production industry, large volumes of wastewater are generated containing great quantities of organic matter that requires y safe disposal or utilization. As a result, management of poultry wastewater is of great concern worldwide. However, problems associated with wastewater disposal are a well-known phenomenon. Nevertheless finding solutions to treat different waste types are not always an orderly method to solve and this have cause a lot of adverse effects on the receiving environment. In the current study, chitosan was synthesized from shrimp chitin to determine its usefulness in removing heavy metals from meat wastewater. Factors for example yield, moisture and ash content and deacetylation (DDA) were tested as well and results showed that chitosan was a source from shrimp chitin. Structural properties such FTIR, SEM and XRD were used to determine the structural morphology, and the final results implies successful isolation of chitosan. Modification of chitosan product was then accomplished via cross-linked chitosan with a series of cross-linking agent; glutaraldehyde, epichlorohydrine, p-benzoquinone s-methylbutylamine and 1,3-dichloroaceone adsorbents. Satisfactory percentages were obtained from shrimp chitosan cross-linked s-methylbutylamine, glutaraldehyde and epichlorohydrine (63–72%) whereas lower yield was observed from chitosan starch cross-linked p-benzoquinone (57%). The usefulness of the chitosan modified products were then investigated in purifying wastewater effluent using HG-AAS. Results of qualitative and quantitative analysis on the elemental content showed the presence of the following elements present in different concentrations: Pb, Cr, Cu, Fe and Zn in the meat wastewaters. Lower concentration ranges (0.01–0.9 mg/L) of these heavy metals were observed for Pb(II), Cr(VI), Cu(II), Fe(II) and Zn(II) after testing the different chitosan cross-linked products (A–E). Among all the metals tested, shrimp chitosan cross-linked with 1,3-dichloroacetone was found to be the most effective product for heavy metals removal. These results also revealed that there is a decrease in the amount of heavy metals present in meat wastewater effluent.

在肉类生产行业中，会产生大量废水，其中包含大量需要安全处置或利用的有机物。结果，家禽废水的管理在全世界引起极大关注。但是，与废水处理有关的问题是众所周知的现象。然而，寻找解决方案来处理不同类型的废物并不总是解决问题的有序方法，这对接收环境造成了许多不利影响。在当前的研究中，壳聚糖是由虾甲壳质合成的，以确定其在从肉类废水中去除重金属的有用性。还测试了诸如产量，水分和灰分含量以及脱乙酰基（DDA）等因素，结果表明壳聚糖是虾甲壳质的来源。FTIR等结构特性 SEM和XRD用于确定结构形态，最终结果表明成功分离了壳聚糖。然后，通过用一系列交联剂交联的壳聚糖完成壳聚糖产品的改性。戊二醛，环氧氯丙烷，对苯醌s-甲基丁胺和1，3-二氯丙酮吸附剂。虾壳聚糖交联的β-甲基丁胺，戊二醛和环氧氯丙烷的收率令人满意（63-72％），而壳聚糖淀粉交联的p收率较低-苯醌（57％）。然后研究了壳聚糖改性产品在使用HG-AAS净化废水中的有用性。对元素含量的定性和定量分析结果表明，肉类废水中存在以下浓度不同的元素：Pb，Cr，Cu，Fe和Zn。测试了不同的壳聚糖交联后，Pb（II），Cr（VI），Cu（II），Fe（II）和Zn（II）的这些重金属的浓度范围较低（0.01-0.9 mg / L）产品（A–E）。在所有测试的金属中，发现与1,3-二氯丙酮交联的虾壳聚糖是去除重金属最有效的产品。这些结果还表明，肉类废水中的重金属含量有所减少。
