The waste sludge from shipping docks contains important elements that can be used as a catalyst after proper processing. The purpose of this study was to remove of amoxicillin (AMX) from the aquatic environment using waste sludge from shipping docks as catalyst in the presence of hydrogen peroxide/ultrasound waves. The catalyst was produced by treating waste sludge at 400 °C for 2 h. N₂ adsorption, SEM, XRD, XRF, and FTIR techniques characterized the structural and physical properties of the catalyst. The BET-specific surface area of the catalyst reduced after AMX removal from 4.4 ${\mathrm{m}}^2$/g to 3.6 ${\mathrm{m}}^2$/g. To determine the optimal removal conditions, the parameters of the design of experiments were pH (5–9), contaminant concentration (5–100 mg/L), catalyst dosage (0.5–6 g/L), and concentration of hydrogen peroxide (10–100 mM). The maximum removal of AMX (98%) was obtained in the catalyst/hydrogen peroxide/ultrasound system at pH 5, catalyst dose of 4.5 g/L, H₂O₂ concentration of 50 mM, AMX concentration of 5 mg/L, and contact time of 60 min. The kinetics of removal of AMX from urine (k = 0.026 1/min), hospital wastewater (k = 0.021 1/min), and distilled water (k = 0.067 1/min) followed a first-order kinetic model ($R^2>0.91$). The catalyst was reused up to 8 times and the AMX removal decreased to 45% in the last use. The byproducts and reaction pathway of AMX degradation were also investigated. The results clearly show that to achieve high pollutant removal rate the H₂O₂/ultrasound and catalyst/ultrasound synergy plays a key role.

来自船坞的废物污泥包含重要元素，经过适当处理后可用作催化剂。这项研究的目的是在过氧化氢/超声波的存在下，使用船坞产生的污泥作为催化剂，从水生环境中去除阿莫西林（AMX）。通过在400°C下处理废渣2小时来生产催化剂。N ₂吸附，SEM，XRD，XRF和FTIR技术表征了催化剂的结构和物理性质。去除AMX后催化剂的BET比表面积从4.4降低 ${\mathrm{米}}^2$/克至3.6 ${\mathrm{米}}^2$/G。为了确定最佳去除条件，实验设计的参数为pH（5-9），污染物浓度（5-100 mg / L），催化剂用量（0.5-6 g / L）和过氧化氢浓度（ 10-100 mM）。在pH 5，催化剂剂量为4.5 g / L，H ₂ O ₂浓度为50 mM，AMX浓度为5 mg / L和pH为5的催化剂/过氧化氢/超声系统中，AMX的最大去除率（98％）获得了。接触时间为60分钟。从一级动力学模型（k = 0.026 1 / min），医院废水（k = 0.021 1 / min）和蒸馏水（k = 0.067 1 / min）去除AMX的动力学（${\mathrm{[R}}^2>0.91$）。催化剂可重复使用多达8次，最后一次使用中AMX的去除率降低至45％。还研究了AMX降解的副产物和反应途径。结果清楚地表明，要实现较高的污染物去除率，H ₂ O ₂ /超声波和催化剂/超声波协同作用起着关键作用。
