Eaves view parameter to action

I have a view that list my users, it's basically in the default generated by asp.net mvc with entity, the data is in a table, and inside this table I have one:

@Html.ActionLink("Aprovar cadastro", "Aprovar")

And I have within the controller Action:

 [HttpGet]
    public ActionResult Aprovar(int? Id)
    {
        if(Id == null){return new HttpStatusCodeResult(HttpStatusCode.BadRequest);}
        else { 
               //A função será implementada aqui
        }
    }

Basically I need to pass the ID of a specific user to this controller, but I'm not getting success.

Follow my view:

@model IEnumerable<ApegaPet.Models.ApplicationUser>
@{     Layout = "~/Views/Shared/_SideNavbar.cshtml";  }
@{
    ViewBag.Title = "Avaliar_Ong";
}


<h2>Avaliar requisição de cadastro de Ongs</h2>
<table class="table">
    <tr>
        <th>
            @Html.DisplayNameFor(model => model.nomerazao)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.endereco)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.telefone)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Name)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Email)
        </th>
    </tr>
    @foreach (var item in Model)
    {
        <tr>
            <td>
                @Html.DisplayFor(modelItem => item.nomerazao)
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.endereco)
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.telefone)
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.Name)
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.Email)
            </td>
            <td>
                @Html.ActionLink("Aprovar cadastro", "Aprovar")
            </td>
        </tr>

    }
